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

Summary

In this chapter, we've explored a number of different ways you can visualize graphs of data. D3 provides a number of different standard tools and techniques to visualize these data structures. A very versatile one is the d3.force layout. With this layout, you specify how the various parts of the graph (the nodes and the edges) influence each other, and by running the simulation, D3 moves the elements to their correct positions. While very versatile, it can quickly become unreadable when the number of interconnections increases. For an alternative to the force layout, D3 provides a chord layout. With the chord layout, we can easily visualize more complex interactions in a compact visualization. The last visualization we showed in this chapter uses a matrix layout, where we created a big table that allows you to quickly see the links between elements without having to follow lines or ribbons.
