NAME GraphViz - Interface to the GraphViz graphing tool DESCRIPTION This modules provides an interface to layout and generate images of directed graphs in a variety of formats (PostScript, PNG, etc.) using the "dot" and "neato" programs from the GraphViz project (http://www.graphviz.org/ or http://www.research.att.com/sw/tools/graphviz/). Note that you need to download and install the GraphViz programs ("dot" and "neato") from either of the URLs above. See the documentation for more information! Note that Marcel Grunauer has released some modules on CPAN to graph various other structures. See GraphViz::DBI and GraphViz::ISA for example.
