In an attempt to assist in visualizing (and debugging) some rather
hairy data structures, I'm looking for a simple node-grapher package
for Common LISP, to display using the X Window System.  I have access
to Sun CL 3.0, and X11R3, and can retrieve whatever pieces of software
I need (CLX, CLOS, CLUE, etc.) via FTP.  What I lack is money, and the
time and desire to write for myself what someone else may already have
done, or have experience using.

More specifically, I at least need to be able to draw labelled boxes
with arrows going among them -- i.e. a directed graph of some kind.
If one were also able to click on said boxes or arcs with a mouse and
have an association signalled back to LISP somehow, that would be even
nicer.  Higher level functionality would be even more desirable to me,
but anything which would allow me to avoid mucking about with X11
primitives (i.e. implementing my own toolkits & widgets) would be
greatly appreciated.

You will note that I've focussed on CL and X, in the hopes of finding
a generic and non-proprietary solution, but pointers to (and
experiences with) working and/or proprietary software (and prices)
would also be welcome.  Thanks.
