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.

Chapter 6. Designing Transitions and Animations

In the previous chapters, you learned everything about responsive visualizations and interactions. Now, we want to make them beautiful and bring them to life using transitions and animations. In this chapter, you will cover the following:

  • Understanding why we use JavaScript for Web animations

  • Implementing a simple animation using D3 timers

  • Learning about interpolation function and how they are used in D3

  • Learning about easing functions and how they are used

  • Understanding the concept of Bézier curves

  • Implementing attribute and path transitions

  • Understanding the main problems of shape tweens

In the first section, you will learn about different web standards used to animate DOM elements, and you will learn how to compare their advantages and disadvantages for animating visualizations. This will help you understand why we use D3's built-in animations and transitions rather than SMIL or CSS animations.

In the second section, we will cover the main concepts...
