Graphviz

Graphviz is a set of graph visualization tools, user interfaces, filters and libraries. This work has been one of the cornerstones of our research for more than ten years. One goal is to automatically produce good concrete diagrams of graphs and networks, that approach hand-made diagrams in quality.

Information Visualization Research and AT&T Labs researcher Bill Cheswick collaborated with Lumeta Corp. and Matt Dresdner at Mercury Seattle to make artwork for an Internet map poster. Click on the image at the right to download the poster (3.2 meg PDF file).

Recent work in graphviz is aimed at problems of scale. There are many problems whose solution involves rendering and interacting with networks whose size ranges from thousands to hundreds of thousands of nodes. In 2008 we expect to release sfdp for layout and a compatible OpenGL-based viewer named smyrna.

Graphviz has been applied to hundreds of projects. Source code and binary executables for common platforms are available. See graphviz.org for information.
