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.

Shape and Layout Generators

D3 is a data-driven data visualization library, but not a charting library. It contains no predefined chart types, but it helps you apply standards such as SVG and Canvas to create absolutely any chart that you can find in a popular charting library, without being limited in any way.

Classic chart types are created in SVG or Canvas with the d3-shape module; this is а complete library for drawing geometric shapes that are commonly used in data visualizations. This is the module you need if you want to create line charts, area charts, pie and doughnut charts, and radial charts.

Eight shape generators are provided for shapes such as lines, arcs, and areas. They return functions that receive structured data and generate SVG path strings or Canvas path commands, which can be bound to graphical elements in your page. This includes preconfigured symbol...
