You can try vcg -- a visualization tool for compiler graphs by
Georg Sander and Iris Lemke @ Univ. of Saarland.  You can get it
from ftp.cs.uni-sb.de:/pub/graphics/vcg.  vcg runs under X11, does
automatic graph layout using a variety of algorithms, produces
multi-colored PostScript output etc.  It expects graph input in a
simple language; it should be easy to write a simple translator
from Scheme to vcg input.
