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.

Until now, you learned a lot about animation, timers, interpolation, and easing, but does it really need all of this to do simple animations in D3. No; luckily, not as long as we use simple transitions. A Transition is an animation from a start state to one end state. The term is often used for animations in general and vice versa, but I want to emphasize that a transition is a simple animation that is defined by two states only; here, the interpolation between these states is automatically created from these states.

D3 has a very powerful support to create transitions. The only thing we have to do is to provide the starting state, call the .transition() method on a selection, and finally provide the ending state and D3 will take care of the rest. The .transition() method will return an object that is very similar to a selection and has most of its methods. In addition, it provides the .duration(duration), .delay(delay), and .easing(easingType) functions to define the duration...
