I agree SVG is not the way to go, but I have reservations about
depending on graphviz.

I always thought the idea of levels might make sense here - each "part"
of Axiom being a single graph node which links to further graph trees.
Clearly Axiom is far too complex to be usably visualized in any one
graph.

For static graphs I agree, but I don't think it can do hyperlinking to
source files. I think what we want is something that generates a
layout using the algorithms of graphviz and then applies that to
generate the xypic or pstricks TeX needed for display.
Remember, one of the goals is to eventually publish the entire Axiom
system via lulu in book form, so to some extent we must always keep
that in mind. And I have a hunch hyperlinked pdfs are probably going
to be a favorite for web distribution ;-).
