Overview of this book

Do you want to make sense of your data? Do you want to create interactive charts, data trees, info-graphics, geospatial charts, and maps efficiently? This book is your ideal choice to master interactive data visualization with D3.js V4. The book includes a number of extensive examples that to help you hone your skills with data visualization. Throughout nine chapters these examples will help you acquire a clear practical understanding of the various techniques, tools and functionality provided by D3.js. You will first setup your D3.JS development environment and learn the basic patterns needed to visualize your data. After that you will learn techniques to optimize different processes such as working with selections; animating data transitions; creating graps and charts, integrating external resources (static as well as streaming); visualizing information on maps; working with colors and scales; utilizing the different D3.js APIs; and much more. The book will also guide you through creating custom graphs and visualizations, and show you how to go from the raw data to beautiful visualizations. The extensive examples will include working with complex and realtime data streams, such as seismic data, geospatial data, scientific data, and more. Towards the end of the book, you will learn to add more functionality on top of D3.js by using it with other external libraries and integrating it with Ecmascript 6 and Typescript

Matrix diagram

For the last visualization of this chapter, we're going to create a matrix diagram. With a matrix diagram, we visualize the graph of nodes as a single matrix. For this example, we'll visualize the most important Simpsons characters as they appear together in a scene. The result that we'll create is this:

This visualization provides the following features:

  • It shows a matrix where the intensity of the color reflects how often characters appear together in a location.
  • When you hover you mouse, it changes the opacity of the row and column to better identify the two characters the value applies to.
  • When you click on the visualization, it changes sorting order. By default, the sort order is on the total amount of appearances a character has. If you click, it changes to sort on the number of unique characters the character appears with.
  • At the bottom, the value of a specific matrix cell...
