Things like that are kind of interesting. I saw some really good stuff on one of the presentations which was animated based on visualization. It's really, really good but you can't come and stop it and drill down. The point is that various forms of data visualization have very specific context and they carry only a certain amount of information.
And, remember the other thing is that data visualization is now going to the point where, on the one hand, we’re using visualizations in order to better understand data; but, on the other hand, we have a lot of data visualization with poor communication.
And just because I understand a particular way of looking at data doesn't mean the guy that I send it to is going to understand that. I think there’s an awful lot of work to be done in for people to properly understand what data visualizations options are, what they mean, what you missed, what you get.
Tables are great but as soon as you have several million rows of tables it’s not so great. You pretty much have to visualize it to get any idea of the shape of the data unless you are going to do something simple, such as, find the outliers by sorting it. You are pretty much lost as soon as you are coming to really big samples of data.
