From: north@ulysses.att.com (Stephen C. North) Subject: free samples of directed graph layouts by mail Keywords: graph layout, DAG, embedder Date: 25 Jun 93 18:28:29 GMT Organization: AT&T Bell Laboratories, Murray Hill
I have created an experimental service for remote users to try some of our graph layout programs through Internet mail, for research or educational purposes. I'm looking for a few friendly users to try this service. The programs are:
dag (directed graphs, old, program, works with some USL C++ utilities.
This may have unintentionally sparked the apparently misdirected
discussion of "DAG classes" in one newsgroup recently.)
dot (directed graphs, newer algorithms, better layouts, more features)
neato (undirected graphs, compatible with dot, Kamada-Kawai spring embedder)
You can ftp PostScript files of documentation from dist/drawdag/*.Z on research.att.com
To draw graphs, send a graph file to drawdag@toucan.research.att.com and give the command line in the Subject header. For example,

File arguments are disabled for obvious reasons. Please let me know if you hit any snags. There is a reasonable limit on graph size and probably number of invocations from a given site/account. (If you use it that much, AT&T's Intellectual Property Division sells binary executables; their number is 800-462-8146).
