To get started, download Gephi from https://gephi.org/ and install it locally on your machine. At the time of writing this book, the stable version is 0.9.1, which we will use throughout. Upon opening the Gephi application, you will be prompted a welcome message and can choose from a few examples to explore. We will use Les Miserables.gexf to familiarize ourselves with the tool. We will discuss the GEXF file format in more detail later; for now, let's just focus on the application. The underlying graph data of this example consists of vertices representing characters of the piece, Les Miserables, and edges denoting the association of characters, weighted by an assessment of the importance of the connection.
Gephi is a very rich tool ...
