RE: Handling data flow diagrams and system flow charts

[Alex Midence <alex.midence@xxxxxxxxxxx>]

Thanks for confirming my suspicions, Tim.  I'd come across Graphviz some years ago in my search for tactile diagrams and such and didn't pursue it because I came across a windows-based package called Deep View written in Java by someone doing his doctorate on whether or not blind people would get much out of flowcharts and things.  Turned out, I didn't need it after all which is just as well since Deep View was buggy but I always meant to look at Graphviz again.

Graphviz is what I've used when in this situation. In fact, it is one of the easiest ways to generate diagrams I've ever used. Essentially, you use the graphiz 'grammar' to specify the nodes and arcs of your diagram and leave it to graphiz to do the layout. In most cases, it does a very good job. You can specify different node shapes and different styles of arc such as directed, bi-directional etc. There is a mode for emacs, though I never really used it. There are also a number of different latex packages to incorporate graphviz into latex docs, though I usually just generate an image and use one of the latex packages for putting an image into a document rather than gemnerate actual TeX to insert into your document.
