We appreciated the recent article here that mentioned using 'dag' to lay out
flow graphs. 'dag' now has a successor, 'dot' ("Dag of Tomorrow") with some
improved layout algorithms and new layout features. We have made these tools
available as an experimental service via Internet mail. If you mail a graph
file to, the server mails back a PostScript
file of the layout as a reply. If you would like to try this, ftp to and look in dist/drawdag. "mail_server" contains further
instructions and "" is a user's guide. We also have written an
interactive, programmable graph editor that runs as an X windows front end to
dot. While this doesn't run over Internet mail, we would consider making
the software available to a few outside academic groups, if there were
applications or research of mutual interest.
