On linux, the graphviz package install a bunch of libraries and a bunch of commands. The commands are: ,---- | Graph layout programs | dot filter for hierarchical layouts of graphs | | neato filter for symmetric layouts of graphs | | twopi filter for radial layouts of graphs | | circo filter for circular layout of graphs | | fdp filter for symmetric layouts of graphs | | All of the filters work with either directed or undirected graphs, though dot is typically | used for directed graphs and neato for undirected graphs. Note also that neato -n[2] can be | used to render layouts produced by the other filters. | | Graph drawing programs | lefty A Programmable Graphics Editor | | lneato lefty + neato | | dotty lefty + dot | | Graph layout enhancement | gvcolor | flow colors through a ranked digraph | | unflatten | adjust directed graphs to improve layout aspect ratio | | gvpack merge and pack disjoint graphs | | Graph information and transformation | gc count graph components | | acyclic | make directed graph acyclic | | nop pretty-print graph file | | ccomps connected components filter for graphs | | sccmap extract strongly connected components of directed graphs | | tred transitive reduction filter for directed graphs | | dijkstra | single-source distance filter | | bcomps biconnected components filter for graphs | | gvpr graph pattern scanning and processing language | | prune prune directed graphs | | Other | gxl2dot, dot2gxl | GXL-DOT converters `---- There is no "graphviz" executable as such. I would expect a similar setup on MacOS. The man page refers to http://www.graphviz.org/Documentation.php for more info. HTH, Nick
