I'm not sure about this. Why do we constantly need new ways of presenting data? My main concern is that eventually it becomes easy to read and interpret data, especially for people that are not used to it, that are less data- or science-savvy in a way. That it's accessible. It's good to try to find better ways to present certain cases, but also it's only needed as far as it's useful, and otherwise I feel consistency is way better instead of keeping churning out new ways to look at it that require an effort on the consumer part (no matter how beautiful / well presented this is) to figure out what they want to know out of it. Innovation for the sake of usefulness is good. Innovation for the sake of innovation feels... definitely not as good (although I wouldn't discard it completely).
