I can (and in fact I did already) recommend pigale as a program to draw graphs
(in the graph theoretic sense). Once upon a time a wrote a (very buggy)
graph-package for maxima which used pigale to display them.

The key feature of pigale is that it has excellent algorithms to draw --
especially small, planar -- graphs, and the user can try out various algorithms
interactively.

For large graphs I'd like to recommend tulip (from the same department, in
fact). 

I know the developers, so if anybody is going to write a domain "graphs"
(belonging to the category "matroids"...) he should look at it.

I also would like to express my agreement with Bill: we should not try to
deliver an all in one package! There is a lot of very specialised software
around, we should interface with it, but not rewrite it! And I think that axiom
should run independently of it.
