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. -- Michaël ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

May not exactly be what you're looking for, but I have used the TeX `xypic' package, which comes with `print/teTeX', for drawing directed graphs. From your other messages, I understand your graphs have a large number of vertices. I don't know how `xypic' scales for large graphs. The ones I've used it for were quite small. Moreover, the input format for `xypic' is similar to a matrix in LaTeX. The package essentially views the graph as a matrix, each of whose entries is a label for a vertex together with vectors that represent the edges starting from that vertex. Raghu. -- N.
