Graphviz can cope with hundreds of nodes, simply it will take some time
to draw the graph and the graph will be hardly readable. There is an
example for the directed graphs of FreeBSD ports tree (directed by
dependency between ports), which has thousands of arrows, here:
see in particular the function write_dotfile.
I hope this will cut your work by still some hours ... maybe it will be
finished before beginning?
