graph layout module?

[Harry George]

I have a shop scheduling task, thus roughly rectangular layouts
with task bars and pred/succ arcs between tasks.  Any convenient tools
for this?

Probably need a simple gui for debugging, but final result is a 36
inch printed plot.  I can imagine, e.g., generating XML for dia to
visualize, then print to postscript.

Needs to operate in both UNIX (AIX, SGI, Linux) and WinNT
environments.
