While gearing up on a content management project, a few developers were wrangling with how to share solution diagrams between Visio and OmniGraffle. While there is a level of compatibility between the two, its not ideal. While researching, I went off into a related tangent, a cross platform tool that I can manipulate from a text editor or programming language, and ended up reading about Graphviz.
Graphviz – command line tool and DSL (dot) to define and render graphs and diagrams.
Doesn’t sounds like much, but check out this magic: Visualizing traceroute output with Ruby and Graphviz or how about Maven based dependency graphing?

Orgmode.org: org-exp-blocks.el: pre-process blocks in org-mode files in Emacs to generate diagrams – rocking!
Bernt Hansen’s fantastic Org Mode – Organize Your Life In Plain Text! is a working example of the above org-mode use case (and a great org-mode tutorial)
