Site outline or architecture software

Something to create wireframes of sites, preferably shareware

Howdy all,

Does anybody have a suggestion for a simple, cheap software application for OS X to create site outlines, diagrams, architectures, or whatever you want to call them? I just want something I can use to visually create a site structure, lable nodes, move stuff around, etc.

I did a search on WW, but couldn't find anything. Thanks for any insight you might have.

I'm not aware of any free products but have a look at OmniGraffle:

That looks great. More than I was looking for, but I might have to spring for it anyway. Thanks for the tip.
