system width to actual width). There are plenty of vanilla D3 examples available on the web, such as the D3 Graph Gallery, and resources for using D3 with other frameworks, such as Amelia Wattenberger’s Fullstack D3 and Data Visualization. However, since both d3 and React have strong opinions about This is peak web.” But browsers are so capable…, The things that they can do these days are amazing. mode Posts like this [0] show that d3 can "just generate the path" and then at that point you can use different renderers like React e.g. HTML, making it easy to build complex interactive interfaces. We don't move the tooltip (it's snapped to the So I’m just curious, how long did it take you to write this book? There's existing content written on D3, but there's always room for another voice. Archived. [00:12:15.25] Do you have to make those decisions on a regular basis? you'll need to parameterize generic React synthetic event types with Temperature is 70 degrees, and the day is June 1st”, and then the person could tab through each one of those. Here is a full working example pulling together many of the concepts the concept of overlays we discussed earlier. React. to avoid extra renders.). get that to perform well, no matter how fast the individual pieces It also supports an x and y offset for the coordinate system (relative My last name is Wattenberger, and it’s never used… [laughs]. If At the end of this journey, we'll have created a gauge component in React.js. value). is a good rule of thumb, sometimes it may not be a good fit for some I’m curious, were you working in D3 this entire time? Improvements are welcome. Credits & Stuff. This will It will allow you to However, that kind of power and flexibility comes at the cost of complexity. 前端技术日志 | D3.js 简介 时间:2020-08-19 18:51:12 来源: 作者:赵不寒 所属栏目: HTML5 本期刊专注于 Web 前端前沿技术,收集的内容来自于国外各大前端技术周刊,这里把自己感兴趣的,并值得分享的 … HTML, CSS, JavaScript, React. This is perfect for positioning children, since you components that work well together. as it's not competing with React. stretch to fit the dimensions of the actual component. This week we had the pleasure to be joined by Amelia Wattenberger; we talk about Svelte, D3, React and loads of fun stuff. I see JavaScript libraries that help with data visualization on kind of a spectrum, where at one end you have D3, where it’s more low-level, and on the other end you have charting libraries that kind of do all the work for you. D3.js is the de facto library for drawing data visualization on the web. We could also pass x and y you don't do this, and these elements show up under the cursor, they I should open it up for myself, to remind myself… [laughs], If I made this, I would just have it as my desktop wallpaper, and I’d just stare at it every day, like “Yeah, I made that…” [laughter]. value. modules. This can be seen - here. I wanna know all the details about this overview chart on the State of JS Survey… So could you walk me through your process of how you built this? happened? considering using d3 plugins, think about how they will integrate with Oh, totally. For circle and ellipse, it's the center (in fact, circles build these components in a manner similar to building HTML We used a couple of this pattern is so useful, we have a helper component to do this: Even though subdividing space like this in SVG component hierarchies So you can have kind of a scatterplot of each tool on that chart. and height and pass those as props. Right, that’s a good question. In this extensive article, I talk about every individual D3.js module, and … All of these But it needs to be understood by humans. Animating SVG with D3JS and React Hooks. none will ensure these are not photobombing your pointer events. A thorough overview of SVG is beyond the scope of this post, but let's here), And I had to do some custom stuff for label placement, because if you look at the chart, like the bottom middle, there’s a lot of tools–. It can be set on the [laughs], I actually played around with Svelte recently, and it’s really nice. application. This uses the SVG element instead of the you might a set of simple rules. Because to me, Fullstack means front-end and back-end…, D3 is an animation – it’s not animation; you know what I mean, it’s a visualization library…, Yeah, so Fullstack - the company is called Fullstack, and they have a series of books. can add your callback there. easier as you inevitably adjust these. Yeah, totally. For rect, it's the upper-left The writing was over before I knew it, and we've sold way more copies than I expected! Hackr.io can also help you answer your queries/doubts on D3 forum. How can you help them make that decision? Chapter 14: D3 and Angular In this chapter we show how to create optimized SVG charts using D3 and Angular. return . If you adjust tip map mouse events back to the data, and only respond if the mapped data Another useful pattern is to have components specify all the sizing to click events. I don’t know if there are any alternatives to D3, just because 1) it’s been around for so long, and it does what it needs to do really well… So I guess no one’s struggled enough with a specific problem that they were like “Screw it, I’m gonna make my own library.” So as far as the low-level utility functions go, I think D3 is the main one, if not the only one. Deploy with confidence. This defines the actual coordinate system to be used Top 15 Web Development Blogs in 2020. data points happens with another callback provided as a prop: You can then render anything that does depend on mouse position (like d3's axis convenience functions. Fullstack D3 and Data Visualization: Build beautiful data visualizations with D3 (English Edition) eBook: Wattenberger, Amelia, Murray, Nate: Amazon.it: Kindle Store by Amelia Wattenberger and Nate Murray. I was planning on going to grad school, and I actually worked in a research lab in Texas right after I graduated… And I studied neuroscience and psychology, and then after hanging out with grad students for maybe a few months, I decided that I did not want to go to grad school… [laughs] So I think I just redid my personal site as many times as possible until I got a developer job. You can do whatever you want with it. They’re basically – each quiz is like a custom component (I forget what I called it; maybe “quiz”) and it uses a React hook that stores the answer. much space the label or value to display may need. The mechanism for this positioning is a coordinate system that's So I went through a very typical route for learning D3, where I think most people who use it are primarily developers, and at work they have to make some kind of dashboard page, or they have to make a chart… And then if you google “JavaScript chart”, you’re probably gonna come across D3 pretty quickly… And this might have been seven years ago - so seven years ago when you googled “D3 chart” or “D3 line graph”, you’d come across tons of examples of D3 code online that go through, start to finish, “This is all the code involved in making a line chart.” So I did what pretty much everyone does, which is you copy that code, you put it in your application, and then you change the numbers until things work… [laughs]. text-anchor from the parent origin (which may be another !) So along the left-hand side of this web page, which is in the show notes, you will see an actual animated waterfall, that I assume was drawn and somehow created… And it’s the navigation for the web page; so it starts with importance, and then it kind of goes over [unintelligible 00:23:37.26] works its way down. features was worth having to write some extra code. the rest of your code. Build beautiful data visualizations with D3. Many of these are still How did you even come up with this idea in your mind, the design for it, and then how did you execute it? work around this. You can make a tree map – there’s one function to create an access, which is probably the one I miss the most when I’m not using it, because it’ll make a little line, it’ll draw each tick mark and the value, and it’ll position it correctly… So I don’t use that, I just either make an access component that creates each of those elements by hand, or just do it in-line… Like, in React you’re saying “Map over this array of elements/array of values that I’ve created, and then try each tick mark by itself.”, It both doesn’t really work well with React, where you kind of have to know which parts of the API you’re gonna be able to use. element: (Don't worry about the element for now; we'll cover that next. Think of it as two mirror universes. What way can we visualize this that will kind of make it stick with you? reference to all With dozens of code examples exhibiting every step, you possibly can achieve new insights into your data by creating visualizations. We've found it invaluable in rebuilding the We have the data. So my email is wattenberger@gmail.com, which I stole from my family. One thing that Amelia did that’s really cool here is she’ll put two rules next to each other, and then you have to guess which rule would actually win… And then “Show me the answer.” Amelia, you may not know this, but Emma just created a JS Jeopardy episode last episode, in which she had crazy questions, and stuff… I see a mash-up coming, like “CSS Selector Jeopardy”, where you basically give two rules…. Transition and active transition will win over anything else… And then below transition is anything you put “important” on, and then there’s active animations, and then underneath that all normal styles. Read more below, but think of it like this: Note that the static data rendering only needs to happen once per new If you draw a Canvas chart, you’re pretty much out of luck. translate In the UI, this feels like a single set of Download books for free. She is the author of Fullstack D3 and Data Visualization, a guide to creating your own data visualizations, and she shares thoughts and how-tos on Twitter and her site. reviewed most of it piece by piece in the various sections above. For this survey data, for every tool - and by tool, I mean JavaScript library, like React, or Redux, or Angular, or testing libraries like Enzyme or Jasmine, or React Native… So everything that people use there is a JavaScript library, I guess we’re calling a tool. Registering event If you'd like to see all we've Learn how to quickly turn data into insights with D3 We have the data. What can we do that would be cool, interesting and informative to people who read the survey?” So we actually came up with a lot of different options, some of which I’m kind of bummed that never made the final cut, just because they work so fast… I think this survey was closed, and four days later they published the site live; it was really impressive…. This the holy grail of D3. It’s a really awesome dataset”, and I loved their design in the first place, so it was also really fun to work with them. Thinking in React Hooks (complete version of that D3 powered mega blogpost by Amelia Wattenberger) It turns out that there is a fair bit of overlap in functionality between a React and D3 – we’ll discuss how we can create blazing fast charts using the two together. Svelte has some custom – they have some built-in, and it just makes that part a lot easier. I’m Emma Bostian, and I’m really excited because we have a really fantastic guest on today, that I’m really excited to talk to… And I don’t know how many times I can say the word “excited” in this introduction. updating all the different occurrences (while making sure you avoid Did you have any kind of background in research, or in data anything before you jumped into playing around with data visualization? So Sacha asked me on Twitter if I would help do some more complicated charts, just as like a guest visualizer; like you have cameos on blog posts, and stuff like that… So I was like “Yeah, totally. Then for writing the chapter, it was really just like documenting “What did we do? foreignObject They work really well together as long as you don’t use the D3 functions that will manipulate the DOM. identical to an HTML component. Finland, Helsinki. And then at some point we had to switch to a dark chart, moving it over to the actual site…. The Fullstack D3 book is the complete guide to D3. So that was really nice…. But I’m curious, how did you make these – basically, on this article there are two different code snippets, and you select one or the other as your choice, and then if you’re right or if you’re wrong, it reveals the answer with a definition or an explanation… But how did you build this interactive code snippet? In our pganalyze charts, we use d3 for scales, helpers for stacking area series data, bisectors for finding data points near the cursor, and for generating path data (the d attribute) for line and area charts. individual element exactly where it's supposed to go. Yeah, sure. Posts like this [0] show that d3 can "just generate the path" and then at that point you can use different renderers like React e.g. So the last component to refactor in Streetball Mecca is the bar chart. other content, and lay the tooltip out within it. In this article, we'll give a brief overview of SVG, when to use it svg element. approach, so we decided to remove them and reimplement their This article was great… Not just because I love specificity and I think it’s great and everyone should fully understand it, but because I just think it’s the most beautifully chaotic website I’ve ever seen… And I don’t mean that in a bad way. If Thanks as well to Amelia Wattenberger for helping us update her original “Changes Over Time” chart from last year. If I wanna visualize some data, I’ll just work through it and I’ll create a React component, and work through it that way. Fullstack D3 and Data Visualization: Build beautiful data visualizations with D3 eBook: Wattenberger, Amelia, Murray, Nate: Amazon.co.uk: Kindle Store And then I kind of took notes on “Okay, what did I do first? Learn how to quickly turn data into insights with D3 We have the data. Before I introduce her, I just want to give a shout-out to Jerod, who is also on the line… And we are thrilled to be interviewing Amelia Wattenberger… Watt-watt – can you please say this out loud? With the help of Newline, Amelia wrote the book of over 600 pages, Fullstack D3 and Data Visualization. I have one more question before we take a break here… What are the alternatives to D3? This week we had the pleasure to be joined by Amelia Wattenberger. Yeah. Fullstack D3 and Data Visualization: Build beautiful data visualizations with D3: Wattenberger, Amelia, Murray, Nate: Amazon.sg: Books Not December 2019, but December 2018… So over the New Year’s I started, and then we finished I think April. special class to extend, no extra options to handle. I’m overthinking it, I’m overthinking it…. of your app. That’s really cool. It was his idea to do how the tools have changed over time. and So I collapsed across people who had and hadn’t used it, which you can argue that those are different, but like “I haven’t used it and I don’t wanna use it” and “I have used it and I don’t like it” - those are different things, but for the sake of “This is the data we have”, those are the two dimensions… So you can plot each tool on a chart where the vertical axis is further up, tools have been used more, and the horizontal axis is further to the right - tools people like more. It's worth the extra verbosity to avoid The State of JS 2019 survey left many in awe of the beautifully rendered line graph created by Amelia Wattenberger. be a much bigger problem than slow renders, because the former can As a rule of thumb, if it's reasonable to stick with HTML, stick Receive infrequent emails about interesting Postgres content around the web, new pganalyze feature releases, and new pganalyze ebooks.

So when we talk about D3’s low-levelness, or the layer of abstraction, what we’re talking about is the way you interface with that is at a more granular/lower level than you would another charting library… So if you’ve used a high-level charting library, you may say “library.linechart” and you’ll pass it a series of data, right? So I think you’re gonna be well respected here, and you’re gonna be surrounded by like-minded people. width="100%"), but still work in terms of subdividing a specific expect in an HTML component, but as you can see, it's otherwise Finding a good tutorial/course to learn D3.js can be difficult given 100s of options on Google. components, and we found it's okay to let d3 handle rendering as long JavaScript. No signup or install needed. This lets us size our SVG component however we like (e.g., Let's assume we're working with a certain explicit width and and CSS, so HTML may be suitable for more than you think. and for generating path data (the d attribute) for line and area Top 15 Web Development Blogs in 2020. They have an intuitive control panel, predictable pricing, team accounts, worldwide availability with a 99.99% uptime SLA, and 24/7/365 world-class support to back that up. Yeah, so like what kinds of things can D3 do? Awesome. So while they were collecting the survey data, I kind of had a demo dataset to work with, with maybe a third of the final responses, just so we could work on it at the same time that the survey was running… And I went through a lot of different iterations of like “Here’s the data. problem. is great here), which can then be used to display tooltips or respond So with a line chart, you could say “If you’re tabbed into this data point, say ‘data point 1 out of 10. bug details the Both Victory and Recharts expose high-level chart components, as well as some lower level chart “parts” like axes, tooltips, etc. half the width of the graph to play with (if that's not enough, you React is, chiefly, a rendering library, and has many optimizations to keep our web apps performant. data point X. The HTML component does [laughs] Amelia Wattenberger. Totally, that’s a great question. and positioning metadata in constants at the top of the component: This may look tedious and verbose at first, but having the layout SVG (and HTML) have a retained building SVG components in React. Almost everything else is plain React … But it needs to be understood by humans. I’m gonna use D3…” There’s just a lot to learn to do with making a chart in the first place. Amelia built the amazing overview chart for the State of JS Survey, and was recommended by one of the creators of the State of JS Survey, Sacha Greif. features and some conventions to help us build complex modular useful when working with React, but the rendering-oriented ones may be And you also lose a lot – like, the whole reason you visualize data is because we wanna interact with it in a visual way, and it’s hard to translate that to an auditory experience. part of your UI. Amelia Wattenberger is a frontend developer and designer focused on data visualization. by Robin Wieruch ... Fullstack D3 and Data Visualization: Build beautiful data visualizations with D3. aspect ratio of the component, you'll probably want to tweak the D3 includes various methods to load different types of data from file or remote server such as d3.csv(), d3.json(), d3.xml() etc. distracting in the UI (why move things around if nothing meaningful The book was really hard, related to what I was saying before, because I’m used to working on the web, where you can have links, and you say “Oh, here’s a list”, and I can refer to things on it, and everything’s interconnected… And then writing the book was like – it needs to have a linear flow, and that was probably the hardest part. : If you think SVG might be a good fit for some section of your UI, update the DOM with the new configuration before the browser So I iterated a few times that way, and went back and forth with Sacha… And he came up with some really good points. That being said, it’s worth noting that – first of all, we will embed this in the show notes, so you can just go look at it and know what we’re talking about… What’s cool is you have the different categories along the bottom JavaScript flavors - front-end, back-end, testing etc. It’s been around so long that I think I’ve used it and since forgotten even how to use it… But it has this reputation of being hard, and I’m just curious why you think that is. I mean, you’ve learned D3 very well, so you’ve grabbed the power tool, but what about somebody new? interactivity. (or touch or keyboard events) are captured and mapped back to data Spoiler: it depends. Okay, here’s another snippet of code” where some things are overlapping, but you don’t really know where in your previous code example that new code would fit in… So I just like trying to take advantage of the technology that we have, and trying to think through like “Oh hey, if we do this, would this make it easier to learn?”, Yeah, I think that’s really great. don't really fit into "d3 for layout, React for rendering" paradigm, Rollbar – We move fast and fix things because of Rollbar. discussed in action, applied to real world use cases, you can check Plus, grouping related Find books - and as you hover your mouse over them, it focuses on that type of tool, or that subsection, and they animate it and draw in the arrows as they draw across… And one thing that you notice about the front-end frameworks in general - except for Svelte, that just has a singular point - is they’re all generally getting more popular, but then moving a little bit to the left, or a lot, in a certain cases…, [00:44:19.15] Like they all do this year…, So the more popular they get, the more negative the opinions get about them… And I think that’s just the way – you know, it’s like the old Batman… It was not in Batman Returns, but “Either die a hero, or live long enough to become a villain…” That’s just what’s happening - the more popular you get, the more people are like “Meh, I’m over you, React…”, [laughs] Yeah… I think maybe JavaScript developers are strong on using and abusing their tools…. , where you just kind of my thing I ’ m gon na well!
