AGD offers a broad range of existing algorithms for two-dimensional graph drawing and tools for implementing new algorithms. It is a product of a cooperation of groups in Halle, Köln, and Saarbrücken supported by the DFG in the program "Design, Analysis, Implementation, and Evaluation of Graph Drawing Algorithms".

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).

Free Macintosh software for graph theory.

TWaver is a complete suite of Java graphic components for telecommunication operations support systems (OSS).

GDToolkit (also known as GDT) is a Graph Drawing Toolkit designed to efficiently manipulate several types of graph, and to automatically draw them according to many different aesthetic criteria and constraints.

GoVisual-API is a library of layout algorithms that can be integrated into C++, .NET or Java applications. Includes advanced layout for UML diagrams and cluster diagrams.

Links to research groups and software.

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.

Attempts to apply force-directed layout (by Touchgraph) on various datasets, including dmoz.org categories and web site link structures.

Information source for researchers, practitioners, developers, and users working on all aspects of graph visualization and representation.

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

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

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.

A set of java tools for network and graph optimization problems. It features basic graph algorithms and graphical user interfaces. Mascopt is under LGPL license.

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.

A C# graph library with Graphviz support, provides directed/undirected graph data structure for .Net.

JGraph is a freely available Java Graph Component for the visualization and layout of graphs.

A simple graph editor for MS Pocket PC 2002. Supports the GML file format.

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.

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