Overview of this book

Want to get started with impressive interactive visualizations and implement them in your daily tasks? This book offers the perfect solution-D3.js. It has emerged as the most popular tool for data visualization. This book will teach you how to implement the features of the latest version of D3 while writing JavaScript using the newest tools and technique You will start by setting up the D3 environment and making your first basic bar chart. You will then build stunning SVG and Canvas-based data visualizations while writing testable, extensible code,as accurate and informative as it is visually stimulating. Step-by-step examples walk you through creating, integrating, and debugging different types of visualization and will have you building basic visualizations (such as bar, line, and scatter graphs) in no time. By the end of this book, you will have mastered the techniques necessary to successfully visualize data and will be ready to use D3 to transform any data into an engaging and sophisticated visualization.

Chapter 6. Hierarchical Layouts of D3

Part of the process of learning to do cool things with D3 is looking at examples on This is great, as you have a living, forkable code base that you can modify into something specific to your use case, but part of what makes learning D3 difficult is that quite often, these rely on layouts, which are effectively algorithms that restructure data in a certain way. These can seem really opaque if you don't know how they work.


D3 v4 alert! Everything in this and the next chapters has changed significantly with D3 v4. Now more than ever, make sure that you pay attention to which version of D3 an example uses when looking at them online.

Over the course of the next two chapters, we'll be diving into layouts and building a ludicrous number of quick charts. First, we start with hierarchical layouts, which assumes a data structure with parent and child nodes; in the next chapter, we'll look at some of the other layouts, which include things such...
