Overview of this book

D3.js is a JavaScript library that allows you to create graphs and data visualizations in the browser with HTML, SVG, and CSS. This book will take you from the basics of D3.js, so that you can create your own interactive visualizations, to creating the most common graphs that you will encounter as a developer, scientist, statistician, or data scientist. The book begins with an overview of SVG, the basis for creating two-dimensional graphics in the browser. Once the reader has a firm understanding of SVG, we will tackle the basics of how to use D3.js to connect data to our SVG elements. We will start with a scatter plot that maps run data to circles on a graph, and expand our scatter plot to make it interactive. You will see how you can easily allow the users of your graph to create, edit, and delete run data by simply dragging and clicking the graph. Next, we will explore creating a bar graph, using external data from a mock API. After that, we will explore animations and motion with a bar graph, and use various physics-based forces to create a force-directed graph. Finally, we will look at how to use GeoJSON data to create a map.

Using SVG to Create Images Using Code

SVG elements are a way to create images within a web page and are the foundation of D3 and how it works. They use code to create shapes, rather than defining each pixel of an image. This chapter covers how to create various SVG elements within a web page. In it, we will cover the following topics:

  • Base tags
  • Basic elements
  • Positioning
  • Styling
  • Important SVG elements

The complete code for this section can be found here: https://github.com/PacktPublishing/D3.js-Quick-Start-Guide/tree/master/Chapter02.
