RE: Handling data flow diagrams and system flow charts



Hmm.  Would your class take kindly to an automated approach.  There's a web
application based on Ruby called Redmine which is a project management
application.  It makes gant charts and things for you automatically based on
time spent on a given project.  I can't make head or tail of them, of
course, but the sighties think it's the best thing since they started
serving beer cold in summer.  Just a thought.

R us a stats + graphing language:

Neither R or gnuplot seem particularly suitable for producing system
diagrams.
