What this book covers

Chapter 1, Getting Started with D3.js, provides a high-level overview of what makes D3 so interesting. We examine what an SVG element is and set up our machine so that it is ready to create D3 code. We also take a look at this book's approach to learning and how it applies to the applications that we'll build.

Chapter 2, Using SVG to Create Images Using Code, covers the basics of SVG (base tags, basic elements, positioning, and styling). We also look at Bezier curves and how to draw organic shapes with them. We're now ready to learn how D3 can be used to modify these elements.

Chapter 3, Building an Interactive Scatter Plot, explains static scatter plots and a shows how to build a table that displays its data.

Chapter 4, Making a Basic Scatter Plot Interactive, shows you as many useful modules as possible, with examples of daily activities that can be carried out and personal comments based on our experience of using them.

Chapter 5, Create a Bar Graph Using a Data File, covers many interesting use cases that any system administrator will need to run daily. Many other tasks can be performed as we show with customized playbooks. But not every script is considered as good automation. What matters is that the right nodes go from state A to state B with no errors and in a short time.

Chapter 6, Animating SVG Elements to Create an Interactive Pie Chart, shows how a pie chart animates when you remove sections from it.

Chapter 7, Use Physics to Create a Force Directed Graph, shows how to use D3 to create a graph that visualizes relationships between various nodes of data. This can be very useful in scenarios such as graphing a friend network, showing parent/child company relationships, or displaying a company's staff hierarchy.

Chapter 8, Mapping, discusses GeoJSON, what it's used for, and why it differs from more general JSON data. We also cover how to use D3 to create a projection and render GeoJSON data as a map.
