The goal of this part of the book is to outline all the steps involved in taking raw data and transforming it into an insightful, interactive analysis of a graph data set. Various examples will be used throughout this section—such as the graph of people associated with 10,000 e-mails shown in Figure P2-1.
Whether you are exploring e-mails, tweets, market baskets, Internet networks, flight networks, or global trade flows, you usually follow a sequence of steps, as well as use various tools, to transform data into insights through analysis and visualizations.
Table P2-1 provides an overview of the next six chapters. Chapter 3 (“Data—Collect, Clean, and Connect”), Chapter 4 (“Stats and Layout”), Chapter 5 (“Visual Attributes”), and Chapter 6 (“Explore and Explain”) walk you through the major steps, starting from data through to communicating results. Chapter 7 (“Point-and-Click Graph Tools”) and Chapter 8 (“Lightweight Programming) discuss how this is accomplished using either point-and-click graph software or programming.
