Data visualization is such a huge topic at the moment. I think this will be one of the most saught after skills in the coming years. Business brains are constantly trying to figure our what to do with all the big data they collect and these kinds of visualization techniques are going to make a lot of people a lot of money! Creating a picture of the data a business collects seems almost better than the best data warehousing solutions, or at least a huge compliment to them. Knowing how to do this stuff is going to be very lucrative in the next decade. I think @bobsenoff would be very interested in this one.
Sounds like a SAAS startup waiting to happen; the code is open source so it can be hosted and extended. I could see it being useful for analysts looking to wow people at their next meeting without spending hours/days developing charts.
