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

Exporting visualizations as SVG and importing them in an external program

In the previous section, we showed how to export our SVG visualization as an image, but we can, of course, also save the element as an SVG file so it can be imported into external programs, such as Adobe Illustrator, Boxy SVG, or Inkscape.

For exporting SVGs as .svg files, we can use two different approaches. If you use Chrome, there is a Bookmarklet that you can use, and which can be found at When you've installed this Bookmarklet, you can export SVG from any page you want. In this section, though, we'll provide an alternative approach that pretty much follows the same steps that we did for exporting SVG as a PNG file:

  1. We'll once again start by defining the specific CSS style that should be included in the exported SVG file.
  2. Then we combine the SVG and the CSS file into a single SVG string...
