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 4. Making the Chart Responsive Using Bootstrap and Media Queries

In the previous chapter, you learned all about loading, parsing, filtering, and grouping data from real sources. This gives us everything we need to design responsive charts using Bootstrap and Media Queries on some real data. In this chapter, you will learn the following:

  • Learning absolute and relative units in the browsers

  • Understanding what a responsive chart really is

  • Drawing charts with percentage values

  • Scaling charts using the viewBox and preserveAspectRatio attributes

  • Adapting charts using JavaScript event listeners

  • Learning to adapt the resolution of the data

  • Using Bootstrap's Media Queries

  • Understanding how to use media queries in CSS, LESS, and JavaScript

  • Learning the usage of Bootstrap's grid system

First, we will discuss the most important absolute and relative units that are available in modern browsers. You will learn the difference between absolute pixels, relative percentages, em, rem, and many more.
