I think we're going to just disagree here. I would think that the behavior is really irrelevant. As you say, you could do the same thing with an interactive pie chart. The important thing is to be able to capture the intent of the user, which is a structure of data -- no matter what the appearance or behavior. In fact, since it doesn't matter what the appearance or data is, that's a perfect reason why it should be a tag. And that's not even getting into the grid concept. Rank your immediate family members on how much you think they'd like the top 5 TV shows from 2010. Here we have a very complex piece of data, all interrelated, and it belongs under the same tag. The structure of the underlying data is fundamentally different from other things. But like I said, I don't think we're going to agree. I'm just happy you seem to understand my point. The conversation starts, and that's always a good thing.
