I had never heard the term before; after looking it up on Wikipedia, I have never heard of any of the software packages listed. I don't know what I would do with such a tool. If I'd ever needed one, I imagine I'd already have gone looking for it, so I guess that these software visualization tools must be solving problems which don't really exist in my part of the industry. Maybe this is the sort of thing you need if you're trying to wrangle some giant mess of a business app with millions of lines of Java? I don't know, I've never gone near that world.
