Gephi: eye-popping, free graph analysisMay 16th, 2010 | By Vic | Category: Mindmapping software, Network visualization
The latest addition to Mind-Mapping.Org is a mapping application with a formidable collection of exciting and engaging ways of presenting and visually analysing networks – or as maths buffs call them, graphs.
Gephi is an interactive tool for visualizing and exploring networks and complex graphs. ”This is a software for Exploratory Data Analysis, a paradigm that appeared in the Visual Analytics field of research”, they say. It is free open source software.
Its purpose is to help data analysts to uncover patterns and anomalies, or faults during data sourcing. Its use complements statistical analysis, as visual thinking with interactive interfaces is now recognized to facilitate reasoning.
It is used for exploratory data analysis; link analysis; social network analysis; and biological network analysis.
It employs metrics to analyse connectedness of nodes (degree – power-law, betweenness, closeness), density, path length, diameter, HITS, modularity, clustering coefficient.
