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.

Chapter 8. Testing Responsive Visualizations

In the previous chapter, you learned how to create amazing cartographic visualizations using D3.js, projections, and geographic maps. Now, it is time to look into the testing strategies of responsive visualizations. In this section, you will learn the following:

  • Learning about common testing strategies

  • Understanding the difference of unit and integration tests

  • Learning about the importance of manual tests in visualizations

  • Learning how to set up an environment for manual testing

  • Setting up an environment for Unit and Integration testing

  • Running unit tests using Karma on your local machine

  • Running integration tests using TravisCI and Sauce Labs using a testing environment

  • Understanding how the different strategies work together

  • Building a testing strategy that fits your budget

In the first section, you will learn about testing, testing strategies, and different types of tests. You will understand the differences between manual and automated testing and why...
