The graph is very large. All of the information to create the graph
exists in static files (the algebra Makefile and the bookvol10* files).

It would be useful to be able to create portions of the graph
dynamically. Some of the functionality exists in the API domain
(ApplicationProgramInterface), such as getAncestors and getDomains.
Any other functionality is just as easy to add. I'd be happy to help.

In addition, it would be useful to be able to graph some information
related to functions. Where are all of the "integrate" functions and
how are they related? Or to know about a domain by showing the locally
defined functions and the tree of parents whose functions it inherits.

>From a given domain it would be useful to create portions of the graph
of a given distance around the domain. So you could ask for a small
graph of categories and make the limit distance of 3. If the output
was in some standard format (e.g. dot files, html, etc.) it could be
used as input to graph drawing programs.

This is a reasonably straightforward problem and would get you more
familiar with Axiom's hierarchy as well as writing code.

Some of this functionality can be embedded into latex documents which
would make them much more useful. Currently the big graph contains
links to the source code in the books. There are mini-graphs in the
books but the links are not (yet) part of the graphs. It would be
useful to click on the pictures in the book and move to, say, a
parent category's source code.
