Applications

Exploratory Data Analysis: intuition-oriented analysis by networks manipulations in real time.

Link Analysis: revealing the underlying structures of associations between objects.

Social Network Analysis: easy creation of social data connectors to map community organizations and small-world networks.

Biological Network analysis: representing patterns of biological data.

Poster creation: scientific work promotion with hi-quality printable maps.

Metrics ready

Centrality: used in sociology to indicate how well a node is connected. Available: degree (power-law), betweenness, closeness.

And more: density, path length, diameter, HITS, modularity, clustering coefficient.

Technology

Ergonomic interface: no programming skills needed

High-performance: built-in rendering engine.

Native file formats: GDF (GUESS), GraphML (NodeXL), GML, NET (Pajek), GEXF and more.

Customizable by plugins: layouts, metrics, data sources, manipulation tools, rendering presets and more.

Like Photoshop™ for graphs.

Features

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

Layout

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.

• Force-based algorithms
• Optimize for graph readability

Metrics

• Betweenness Centrality, Closeness, Diameter, Clustering Coefficient, PageRank
• Community detection (Modularity)
• Random generators
• Shortest path

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

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.

• Create complex filter query without scripting
• Build new networks from the filtering result
• Save your favorite queries

Data Table and Edition

Gephi has its own Data Laboratory with an Excel-like interface to manipulate data columns, search and transform the data.

• Powerful Search/Replace
• Manipulate columns
• Batch-edit, custom column merge and more

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.

Learn how to use Gephi

Welcome to Gephi! Gephi is an open-source software for visualizing and analysing large networks graphs. Gephi uses a 3D render engine to display graphs in real-time and speed up the exploration. You can use it to explore, analyse, spatialise, filter, cluterize, manipulate and export all types of graphs.
