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.

Quick Start

The goal of this chapter is to get you up and running with D3.js. You will learn how to use the most important modules and walk through a collection of examples that demonstrate how D3 maps data to visualizations. We will start by binding data to HTML <div> elements and paragraphs to create a simple horizontal bar chart, complete with labels, a color scheme, and dynamic scaling, and then bind the same data to SVG, which offers many more possibilities. You will learn how to add gradients, configure animated transitions, and handle events in this chart. Before the end of the chapter, you will even draw a world map using D3. After finishing this chapter, you should have a general working knowledge of D3 that will enable you to create simple charts with your own data.

To follow the examples in this chapter, you should set up a development environment with D3, which...
