D3.js By Example

By: Michael Heydt

Overview of this book

<p>This book will take you through all the concepts of D3.js starting with the most basic ones and progressively building on them in each chapter to expand your knowledge of D3.js.</p> <p>Starting with obtaining D3.js and creating simple data bindings to non-graphical HTML elements, you will then master the creation of graphical elements from data. You’ll discover how to combine those elements into simple visualizations such as bar, line, and scatter charts, as well as more elaborate visualizations such as network diagrams, Sankey diagrams, maps, and choreopleths.</p> <p>Using practical examples provided, you will quickly get to grips with the features of D3.js and use this learning to create your own spectacular data visualizations with D3.js.</p>

Chapter 7. Creating Animated Visuals

We are now going to look at using D3.js transitions to represent changes in the information underlying a visual. We will start with examples for examining several concepts involved in using D3.js to animate the properties of visual elements from one state to another.

By the end of this chapter, we will extend the bubble visualization from Chapter 6, Creating Scatter and Bubble Plots, to demonstrate how we can animate our bubbles as we move through multiple years of data. This will demonstrate the construction of a relatively complex animation through which a user can easily deduce trends in the information.

In this chapter, we will cover the following topics through examples:

  • Animating using transitions

  • Animating the fill color of a rectangle

  • Animating multiple properties simultaneously

  • Delaying an animation

  • Creating chained transitions

  • Handling the start and end events of transitions

  • Changing the content and size of text using tweening

  • Using timers to schedule...
