Introduction to d3.js, v2

Some Key Takeaways!

By participating along with us in the workshop, you'll learn:

  • Learn how to navigate the D3 API reference, and the bl.ocks ecosystem
  • Understand selections and how they work under the hood
  • Get your hands on data binding and how that works with the enter-update-exit pattern
  • Experience building a full chart with scales, axis, and legends
  • Gain an understanding of D3 layouts, in particular hierarchy or force layout

Workshop Details

We'll start by looking at the D3 documentation, which is vast and very thorough, but could be overwhelming to navigate. I'll point out how the docs are structured, and also explore the bl.ocks and blockbuilder ecosystems and how to use them to our advantage. After that, we'll dive right into the code, starting with how D3 selections and data binding work under the hood. After we have a good grasp of those concepts, we'll use enter-append to create our first no-frills bar chart. We'll learn scales and axes to annotate our previous chart, then learn update/merge and exit-remove to transition the chart between different data states. Finally, we'll go beyond the bar chart and learn how to create trees and network diagrams with D3's hierarchy and force layouts.

Is This Workshop for Me?


This workshop is for those that are new to D3.js, or have tweaked the example bl.ocks but haven't yet made their own visualizations from scratch. The goal is to gain an intuitive understanding of D3's core concepts and how they work under the hood, as to equip the participant with the tools to explore and learn the rest of the library on their own. To that end, this workshop isn't meant to be a comprehensive introduction to the whole D3 library, but rather a deep dive into specific core modules.

Any Prerequisites?

  • The participant should have working knowledge of Javascript, as well as HTML and CSS.
  • They should have a basic understanding of SVG shapes and their attributes, in particular rect, circle, and line to complete the exercises.
