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.

Real-time visualization

Networks up to 100,000 nodes and 1,000,000 edges

Iterate through visualization using dynamic filtering

Rich tools for meaningful graph manipulation Profit from the fastest graph visualization engine to speed-up understanding and pattern discovery in large graphs. Powered by its ad-hoc OpenGL engine, Gephi is pushing the envelope on how interactive and efficient network exploration can be.

Layout

Force-based algorithms

Optimize for graph readability Layout algorithms give the shape to the graph. Gephi provides state-of-the-art algorithms layout algorithms, both for efficiency and quality. The Layout palette allows user to change layout settings while running, and therefore dramatically increase user feedback and experience.

Metrics

Betweenness Centrality, Closeness, Diameter, Clustering Coefficient, PageRank

Community detection (Modularity)

Random generators

Shortest path The statistics and metrics framework offer the most common metrics for social network analysis (SNA) and scale-free networks.

Networks over time

Gephi is a the forefront of innovation with dynamic graph analysis. Users can visualize how a network evolve over time by manipulating the embedded timeline.

Import temporal graph with the GEXF file format

Run metrics over time (clustering coefficient)

Graph streaming ready

Create cartography

Use ranking or partition data to make meaningful the network representation. Customize colors, size or labels to bring sense to the network representation. The vectorial preview module lets you put the final touch and care about aesthetics before explorting in SVG or PDF.

Customizable PDF, SVG and PNG export

Save presets

Dynamic filtering

Create complex filter query without scripting

Build new networks from the filtering result

Save your favorite queries Filter the network to select nodes and/or edges based on the network structure or data. Use interactive user interface to filter the network in real-time.

Data Table and Edition

Powerful Search/Replace

Manipulate columns

Batch-edit, custom column merge and more Gephi has its own Data Laboratory with an Excel-like interface to manipulate data columns, search and transform the data.

Input/Output

Gephi can read the majority of graph file formats but also supports CSV and relational databases import.

Spreadsheet import wizard

Database import

Save/Load project files

Extensible

The built-in Plugins Center automatically gets the list of plugins available from the Gephi Plugin portal and takes care of all software updates. There are dozens of community-built plugins that extends Gephi's functionalities.
