- Master data visualization with JavaScript through hands-on examples

Book Description:

Learn D3.js, Second Edition, is a fully updated guide to building interactive, standards-compliant data visualizations for the web using D3.js v7 and modern JavaScript. Whether you're a developer, designer, data journalist, or analyst, this book will help you master the core techniques for transforming data into compelling, meaningful visuals.

Starting with fundamentals like selections, data binding, and SVG, the book progressively covers scales, axes, animations, hierarchical data, and geographical maps. Each chapter includes short examples and a hands-on project with downloadable code you can run, modify, and use in your own work.

This new edition introduces improved chapter structure, updated code samples using ES2019 standards, and better formatting for readability. Chapters were completely rewritten to focus on the most important topics first, with suggested exercises after each section, complete with commented solutions and online step-by-step tutorials. All code snippets are drawn from real-world D3 data visualization projects available in a GitHub repository, which also includes bonus content on integrating D3 into applications and migrating legacy code.

With its practical approach, this book remains one of the most respected resources for learning D3.js and creating interactive data visualizations with JavaScript.

What You Will Learn:

- Bind data to DOM elements and apply transitions and styles

- Build interactive bar, line, pie, scatter, tree, and animated network charts

- Implement interactive behaviors with zoom, drag, and tooltips
