D3 Start to Finish shows you how to build a custom, interactive and beautiful data visualisation using the JavaScript library D3.js (versions 6 & 7)
D3 Start to Finish teaches you how to build a custom, interactive and beautiful data visualisation using the JavaScript library D3.js (versions 6 and 7).
The book covers D3 concepts such as selections, joins, requests, scale functions, event handling and transitions. It also covers general web development techniques such as state management and modularisation. In other words, everything you need to know to build a real world, custom data visualisation.
You'll also learn how to put these concepts into practice by building an interactive data visualisation called Energy Explorer. This is a custom data visualisation that visualises the energy mix of 141 countries. There are 15 separate build steps and you're taken through each step in detail. There's also a code for all 15 steps so you can follow along.
Some of the topics covered are
requesting CSV data using D3
D3 data joins (including joining nested data)
architecting a data visualisation using a layout function
detailed styling using CSS
adding a popup using Flourish's popup library
state management
animations using D3 transitions
data manipulation using Lodash
adding a menu, legend and footer
To get the most out of this book you need to be familiar with HTML, SVG, CSS and JavaScript. If you need to get up to speed with these languages I recommend my book Fundamentals of HTML, CSS, SVG & JavaScript for Data Visualisation. I've bundled both books together at a reduced cost (visit bundle).
You'll also need a text editor (such as VS Code or Brackets), a local web server and a web browser. The book contains two appendices that help you get these set up.
To keep things simple build tools such as webpack aren't used. If you'd like to cover ES2015 modules, webpack and other advanced topics have a look at the Advanced Edition package. D3 version 7 is used in this book.

how to transform the raw data from the World Bank into the required format

how to make Energy Explorer using ES2015 modules and webpack
The Advanced edition is for experienced developers and requires familiarity with Node.js and the command line.
