Preface

Welcome to D3.js 4.x Data Visualization, Third Edition. Over the course of this book, you’ll learn the basics of one of the world’s most ubiquitous and powerful data visualization libraries, but we don’t stop there. By the end of our time together, you’ll have all the skills you need to become a total D3 ninja, and will be able to do everything from build visualizations from scratch straight through to using it on the server and writing automated tests. If you haven’t leveled up your JavaScript skills in a while, you’re in for a treat--this book endeavors to use the latest features currently being added to the language, all the while explaining why they’re cool and how they differ from "old school" JavaScript.
