I know of a few OpenSource project management software actually:

Planner (Gnome, used to be MrProject): http://developer.imendio.com/wiki/Planner#About_Planner
kplato (Koffice equivalent): http://docs.kde.org/stable/en/koffice/kplato/main-window.html
...and quite a few web based ones...

Ahhh...this is one of the apporaches that I had in mind. I was even thinking of creating a "simple" script that coud translate simple "rules" into graphical objects interpreted by either gnuplot, dia, xfig or any other app that takes in a textual format to generate graphics.
