Learning Responsive Data Visualization

Overview of this book

Using D3.js and Responsive Design principles, you will not just be able to implement visualizations that look and feel awesome across all devices and screen resolutions, but you will also boost your productivity and reduce development time by making use of Bootstrap—the most popular framework for developing responsive web applications. This book teaches the basics of scalable vector graphics (SVG), D3.js, and Bootstrap while focusing on Responsive Design as well as mobile-first visualizations; the reader will start by discovering Bootstrap and how it can be used for creating responsive applications, and then implement a basic bar chart in D3.js. You will learn about loading, parsing, and filtering data in JavaScript and then dive into creating a responsive visualization by using Media Queries, responsive interactions for Mobile and Desktop devices, and transitions to bring the visualization to life. In the following chapters, we build a fully responsive interactive map to display geographic data using GeoJSON and set up integration testing with Protractor to test the application across real devices using a mobile API gateway such as AWS Device Farm. You will finish the journey by discovering the caveats of mobile-first applications and learn how to master cross-browser complications.

A simple bar chart

Congratulations, you've gathered all the knowledge to build your first bar chart; and this is exactly what we will do in this section. In the following figure, we will create a bar chart that has axis, scales, bars, and labels.

A simple bar chart

Let's start with a simple setup—a blank HTML page that loads the D3 library from the bower components directory. In addition, we define the crispEdges rendering for path elements in the header:

<!doctype HTML>
<title>Bar Chart</title>
<script src="bower_components/d3/d3.min.js"></script>

      .axis path, .axis line {
        fill: none;
        stroke: #999;
        shape-rendering: crispEdges;
      .data rect {
        stroke: red;
        fill: rgba(255, 0, 0, 0.5);

    // Our code goes here

Now, we can start to write JavaScript inside the script...
