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

Visualizing Graphs

So far, we've seen a number of different data structures. We've visualized linear data with bar, pie, and line charts, and have shown how to visualize nested data using trees and treemaps. An important data structure that we haven't looked at yet is the graph. With a graph, we have a number of nodes which are connected to each other to form a network. In this chapter, we'll look at a couple of different approaches you can use to visualize these kinds of structures.

In this chapter, we'll show the following D3 supported visualizations:

  • We'll start with the force layout. With a force layout, we can create force-directed graphs. In a force-directed graph, the nodes are connected to each other with links. All the nodes and links can exact forces on one another which will result in visually pleasing network of nodes. We will visualize this using data from the Simpsons...
