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.

A testing strategy for visualizations

Now, we have enough information to build a solid testing strategy for responsive visualizations. Note that this is a very opinionated setup based on my experience, and feel free to exchange any layer or tool with your favorite ones. However, keep the general ideas for your workflow.

First, we will use the Chrome browser on the desktop PC while developing. We either use a normal desktop window or we switch to a mobile view in the device mode. This depends on the target screen size and resolution. Personally, I prefer to work in a desktop Chrome and debug and test on mobiles.

While developing, we need to regularly do some manual testing to make sure our visualization looks and feels nice. Running emulators for different operating systems locally is a pain; that's why I prefer syncing a real mobile phone and a tablet via Browsersync to my current Chrome window. If you don't have access to real devices, you can also use Browserstack on your local project.
