I've been hacking a few programs to work with vcg, which
does a fine work similar to graphviz.
I really need the node shape "record" of GraphViz for presenting Petri
net states in a tabular format, but the example at
<URL:http://rw4.cs.uni-sb.de/~sander/html/gsvcg6.html> looks promising:
apparently vcg even allows multiple colours per node label (or multiple
labels per node).
It is trivial to modify the graph exporter of maria to produce graphs in
the vcg input language; everything is in one class, Dotty.C. The
biggest problem might be making vcg interactive. At the minimum, it
should be able to communicate via stdin/stdout and draw graphs
incrementally. Translating mouse and keyboard events to Maria commands
on stdout would be a big plus.
I'd really appreciate your help here, as vcg seems to have more layout
options than GraphViz, and it might be easier to get vcg running
properly (communicating via pipes) on Windows than GraphViz lefty. At
first sight, xvcg seems to lack a scripting language. I cannot estimate
how much time it would take to adapt xvcg to act as a maria-vis
replacement, and I'm afraid I won't have the time in the near future.
But perhaps vcg could be made a noninteractive visualiser of maria?
