I’ve started doing diagrams for the JAAS book. My primary computer is a PowerBook, which came with OmniGraffle, so I started using that for UML diagrams. I then downloaded a trial of OmniGraffle Pro, which has better UML stencils and sorts of other wing-dings.
So far, I like it. It’s not as clean as Together, but it’s also about, what?, 60-100 times cheaper? ;> Also, it has a really good interface: you know, the standard Mac app interface where things just seem to make sense. It looks all-purty too.
I looked into getting Visio (for compatibility, etc.), but MS doesn’t seem to have a Mac version. OmniGraffle will import/export to Visio XML (whatever that is), but until I see it actually work round-trip, I’m suspicious that it’d work too well. We’ll see.
So, all that said, does anyone have recommendations for diagram tools on the Mac? Does anyone have experience using OmniGraffle?

I’ve been using OmniGraffle Pro for some time now and love it. I just wish they made a windows version for everyone else since it is so nice.
I would love to try and Apple Script it to output code. You know of anything that can do that?

Above, (search down for “tolke”), Elliotte Rusty Harold reviews some of the UML class diagram editors suggested to him after he freaks out trying to use ArgoUML, and finds that most are terrible. He too liked omnigraffle.
