I'm happy to continue this discussion in further detail and share my experience. You can get in touch with me at the email address in my profile if you'd like.

You're hitting a very important question in your fourth paragraph about ambiguity of desired effect from interaction. I often catch myself thinking I've heard every use case and built most of them in various viz tools. But I have learned that I am always wrong when I think that. I frequently encounter people asking for new things and it is always a toss-up whether what they want is trivial and novel or impossible and obvious.

I tend to be a data-guy much more than a viz-guy, but I fully understand the value of viz for actually presenting knowledge. Like I said, I'm interested in trying out your tool more.
