Hey, how about that, OSX includes a nice vector/diagramming app called Omnigraffle. Goodbye Visio. This is great for the few charts & diagrams I do. Nice integration with the OS. For example I made a basic shape and dropped a PDF file onto it. The shape now displayed the PDF page. Just as easy to drop the pdf or images into the document and it will make shapes for them (with transparency). Slick. Also includes a bunch of templates for UML, network diagrams, flow charts, and <ack!> org charts. Here's Zeke's kinetic flow chart.
