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.

Manual testing and debugging

Let's start with manual testing, debugging your responsive application locally on your development machine. For this purpose, I created a little dashboard application that is displayed in the following screenshot. The picture is a screenshot from a Chrome window on my desktop computer:

Testing and debugging locally

Running your devices locally has one big benefit: it is super fast, and you can quickly see how the visualization feels. You have control over the device; it's either in your hands or running on your local machine. The following figure shows a typical local development setup:

Changing Device Modes in a Chrome desktop browser

The fastest and most convenient way of quickly testing an application with a different screen resolution is to use the Device Mode setting in the Chrome Developer Tools. You can open it by first opening the Developer Tools (pressing F12) and then clicking...
