Gephi is an interactive graph and network analysis and visualization tool that allows its users to study the properties of graphs and networks in detail, without having to write any code. Gephi supports almost all types of graphical networks including complex networks, hierarchical networks, dynamic networks, and temporal networks. Gephi has a lot of ready-to-use features that allow users to create stunning and informative visualizations. Graph analysis is one of the preliminary steps in the process of studying graphical systems and Gephi aids in that process by freeing the user from requiring knowledge of programming.

Gephi was developed in Java and, hence, is a cross-platform application, which means it can work on Windows, Linux, and Mac OS X. This chapter will take you through the step-by-step process involved in installing Gephi on different platforms. We will also discuss troubleshooting that might be required during the installation process.

This chapter also gives you an overview of Gephi's graphical user interface (GUI) and a basic understanding of various modes available in it.
