[net.micro.mac] Data flow diagrams on the Mac?

al@ames.UUCP (Al Globus) (03/23/85)

I use the Mac for software requirements and design development. One
application I wish I had is something to do graphs, e.g., data flow
diagrams.  MacDraw works OK but something that knew graph structures
and would reconnect edges when nodes are moved would be nice.  I've
heard that such programs exist on the IBM PC (I appologize for
desecration).  It seems
like a perfect application for the Mac.  Is there anything out there?
If so, how well does it work?

P.S.  I am NOT talking about graphs in the Microsoft chart class or
business graphics or anything like that.  I'm talking about graphs
with nodes and edges in the information science sense.
