Data flow diagrams (DFD)

[Eric P <eric maillist gmail com>]

Hi,

Wikipedia tells me that Dia has Data flow diagrams (DFD) support 
(http://en.wikipedia.org/wiki/Data_flow_diagram)

I just installed it, but I don't see the DFD shapes.  The only special shape is an open rectangle used to 
represent a
data source.   Example here; http://mediawiki.advancedgaming.biz/images/3/3f/ReleaseMgmt_1.jpg

Anyway, I'm trying to get my class group to use Dia over Visio for a data flow diagram assignment.

Thanks for reading,
Eric
