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

Line charts that show income growth

A line chart is a very common way of visualizing linear data (for example, time-based data). For our discussion on line charts, we're going to create a chart that shows the increase in income in the US over the last 30 years. We'll show this data indexed to a specific year and the absolute growth. We'll use the following two datasets:

  1. Unadjusted dollars:
  2. Adjusted dollars:

These datasets are based on the US Census data, but have already been cleaned up. We can use the adjusted dollars to show the relative increase in income, and the unadjusted to show the absolute growth in income:

So, while it might seem that people are getting richer, at this point we're basically at the level of 1996, and in no way back before the 2008 crisis. At the top right, you can download...
