Development home of the open source Graph Visualization Project from AT&T and Lucent Bell Labs.

aiSee automatically calculates a customizable layout of graphs specified in GDL (graph description language). aiSee supports 15 basic graph layout algorithms, recursive subgraph nesting, fish-eye views and easy printing. It has been optimized to handle large graphs automatically generated by applications (e.g. compilers).

A toolkit for graph editors and graph algorithms. Unix and Win32 binaries for free download.

ILOG JViews Graph Layout Package simplifies complicated diagrams. The package rearranges complex graph data sets into clear on-screen drawings. Core information represented by nodes and links is much easier to understand.

daVinci Presenter draws automatically large, directed graphs in high quality. It includes a graph editor, navigation features, an API for use by other programs and is available for Windows, Linux, FreeBSD and Solaris in English and German.

yFiles is an extensive Java class library that provides algorithms and components for analyzing, viewing and layouting graphs, diagrams and networks.

This program runs under Windows NT/9x and provides some analysis tools for large networks and graph-drawing capabilities.

PIGALE is a graph editor and an algorithm library essentially concerned with planar graphs. Written in C++ and interfaced with the Qt library, it is particularly intended for graph theoretical research. PIGALE is released under GPL.

Graph Analysis and visualization component software for Java, C++, ActiveX and .NET. Free trial download.

System dedicated to the visualization of huge graphs. It manages graphs with a number of elements (nodes and edges) up to 500,000 on a personal computer. It features 3D visualization and modification. GPL.
