PSGRAPH: PostScript DAG Grapher
The PSGrapher is a set of Lisp routines that can be called to produce
PostScript commands to display a directed acyclic graph. It uses the
same basic algorithm as the ISI Grapher. It is slower than the ISI
grapher, but produces much prettier output than using Xdump to copy an
ISI Grapher screen image to a PostScript printer. It also allows
arbitrary information to be displayed with a node, and can print as
many output pages as are necessary to accommodate large graphs (subject
to PostScript printer limits, typically one or two thousand nodes).
The PSgrapher is small enough and easy enough to use to be included
in other systems without pain.
