Learning Responsive Data Visualization

By: Christoph Körner

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.

Using Bootstrap's Media Queries

As we already discussed in the first chapter, Bootstrap is an awesome library that gets you started quickly with new projects. It includes not just huge amounts of useful HTML components, but also normalized and standardized CSS styles. A particular one is the implementation of Media Queries for four typical device types (five types in Bootstrap 4). In this section, we will take a look at how to make use of these Media Queries in our styles and scripts. A great thing about Bootstrap is that it successfully standardizes the typical device dimensions for web developers; thus, beginners can simply use them without rethinking over and over which pixel width could be the most common one for tablets.

Media Queries in CSS

The quickest way to use Bootstrap's Media Queries is to simply copy them from the compiled source code. The queries look as follows:

/* Extra small devices (phones, etc. less than 768px) */
/* No media query since this is the default in Bootstrap ...
