freeware relationship diagram programs??

[T'ai Chi]

Hi all,

I'm looking for a freeware program that can diagram relationships between people.

Specifically, I want to look at martial arts, and map out the relationships (like lineages) between teachers and students; basically just a bunch of lines connecting teachers to their students.

The reason I cannot use a regular genealogy freeware program, is that a student can have multiple teachers, and many do in the martial arts, but a child cannot have multiple biological mothers and fathers, so the genealogy programs fail here (at least the freeware ones I've tried do).

Any ideas?

Try RFFlow, the demo lets you do everything but may be limited in size of diagram. If you can find version 4.07, the limit seems to be much higher.
