Gephi is an interactive visualization and exploration solution that supports dynamic and hierarchical graphs. It runs on Windows, Linux and Mac OS X. Gephi is open-source and free.
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.
