Templates for data flow diagrams
At the end of this post you will find links to attachments for Visio (DFDTemplate.vst) and Word (DFDTemplate.dot) data flow diagram templates that I recently created. Feel free to use them for homework assignment 1 if you wish but remember doing the DFDs by hand is also completely acceptable.
For both templates, simply copy and paste each symbol whenever you need a new one.
For the Visio template, to edit the text you will first need to click on the pointer tool, then select the relevant symbol, then click on the text tool. The text should now be editable.
