Wrapper classes around GraphViz utilities (dot and neato) for
directed and undirected graph generation. Under Windows, the COM API provided by WinGraphviz is used. These wrappers are enhanced enough just to support relationship_graph_api.php. They don't support subgraphs yet.
The original Graphviz package is available at:
- http://www.research.att.com/sw/tools/graphviz/
WinGraphviz can be installed from: - http://home.so-net.net.tw/oodtsen/wingraphviz/
