I am working on some software that must, as it's final output,

The printout could be generated by a postscript file, jpg, whatever.
Does anyone know of a utility (in ports?) that can take a data set
(for example, a two dimensional array that defines the nodes and the
links between them), and produce a printable graph?
Any help much appreciated.
I think it's possible to use LaTeX for this, as long as you're
willing to provide the document basis, put an \include for the
drawing contents and then have a small processing script that
generates this file. There is some LaTeX document class that
supports graphs, I think. The output would be PS or PDF.
TeX and LaTeX usually come with a tool called METAPOST, which reads
instructions to draw a picture and outputs a postscript file. This is
definitely the best choice to produce figures t put in LaTeX document,
but may be useful in solo operation too. The language for METAPOST is
adapted to notations like z1 = 1/2(z2 + z3) or z1l = z1 + left and z1r =
z1 + right, so it's a really unusual stuff but one gets quickly
accustomed with the basics. There is many web pages providing tips for
meta post, I also recommand a paper written by André Heck on the subject.
