Mott Given posted some misinformation that has caused people to send
me mail about non-existent software I'm supposed to be giving away.

I don't have a general purpose node grapher.  Sorry.

What I do have is a program that draws cons cell trees, and can act as
a read-eval-draw loop for teaching beginning Lispers to think in terms
of cons structures rather than parentheses.  The software accompanies my
book, Common Lisp: A Gentle Introduction to Symbolic Computation.  Versions
are available for Lucid, Allegro, Golden Common Lisp (versions 1 and 3),
CMU Common Lisp, and generic Common Lisp.  Some versions use CLX; some
versions use the IBM PC graphic character set; the generic version just
uses ASCII characters to draw the trees.

The software is available on 5.25 inch DOS diskette, free, from the publisher.
Contact the Benjamin/Cummings Publishing Company, Redwood City, CA.  You
can also FTP it by the following method:

  - open an FTP connection to B.GP.CS.CMU.EDU
  - log in as user "anonymous" any password
  - cd DIRECTLY, IN ONE STEP, to /usr/dst/public/lisp
  - grab the README file and anything else you want

Have fun.
