What is Gephi? Meet this useful network analysis tool

By Dr. Verónica Espinoza, 2022

Gephi is the leading visualization and exploration software for all kinds of graphs and networks. Gephi is open-source and free.

¿What is Gephi?

Gephi is a tool for data analysts and scientists keen to explore and understand graphs. Like Photoshop™ but for graph data, the user interacts with the representation, manipulate the structures, shapes and colors to reveal hidden patterns. The goal is to help data analysts to make hypothesis, intuitively discover patterns, isolate structure singularities or faults during data sourcing. It is a complementary tool to traditional statistics, as visual thinking with interactive interfaces is now recognized to facilitate reasoning. This is a software for Exploratory Data Analysis, a paradigm appeared in the Visual Analytics field of research.

Architecture

The modular architecture allows developers adding and extending features with ease by developing plug-ins. Gephi can aslo be used as Java library in other applications and build for instance, a layout server.

Gephi Architecture

Gephi project was born in 2006 with a prototype called Graphiltre, at a sociology research program…
