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

Using D3 with ES6 and TypeScript

In this section, we're going to explore D3 usage from ES6 and TypeScript. We'll start with how to use D3 from ES6.

D3 and ES6

When developing ES6, you have to take into account the browsers you're targeting. Most modern browsers have great support for the ES6 standard:

But pretty much the one subject that is barely supported is the module support. So for now we have to translate our ES6 code to ES5 so it can be loaded directly into any browser (this is often called transpiling).

We won't go through the complete ES6 specification, but look at a couple of the features which are especially interesting in combination with D3. For a complete overview of the features of ES6 you can look here:
