Overview of this book

This book is a practical hands-on introduction to D3 (Data-driven Documents): the most popular open-source JavaScript library for creating interactive web-based data visualizations. Based entirely on open web standards, D3 provides an integrated collection of tools for efficiently binding data to graphical elements. If you have basic knowledge of HTML, CSS and JavaScript you can use D3.js to create beautiful interactive web-based data visualizations. D3 is not a charting library. It doesn’t contain any pre-defined chart types, but can be used to create whatever visual representations of data you can imagine. The goal of this book is to introduce D3 and provide a learning path so that you obtain a solid understanding of its fundamental concepts, learn to use most of its modules and functions, and gain enough experience to create your own D3 visualizations. You will learn how to create bar, line, pie and scatter charts, trees, dendograms, treemaps, circle packs, chord/ribbon diagrams, sankey diagrams, animated network diagrams, and maps using different geographical projections. Fundamental concepts are explained in each chapter and then applied to a larger example in step-by-step tutorials, complete with full code, from hundreds of examples you can download and run. This book covers D3 version 5 and is based on ES2015 JavaScript.

Technical Fundamentals

This chapter covers fundamental standard web technologies used by D3: SVG, JavaScript (ES 2015), HTML Canvas and standard data formats such as JSON and CSV. It is intended as a general reference to these topics.

Most data visualizations created with D3.js generate SVG graphics. Good knowledge of SVG is important to make the most of D3, but you only really need to know the basics. It’s enough to know how to create simple shapes such as rectangles, circles, lines, and their attributes and styles. It’s also useful to understand how to apply transforms, such as translate, scale and rotate. This chapter includes a quick refresher on SVG that covers these essential topics and a bit more, since the more SVG you know, the more graphical resources you will have to create data visualizations using D3.

All the code examples in this book use ES 2015 (ES6...
