On a more substantive note, this looks really neat. However, as a data scientist of sorts I've found that what people really want is not some sort of interactive 3D visualization, but a well-computed chart showing a sort of natural experiment (e.g. the results of an A/B test) with the right axes. Has anyone used a 3D visualization outside of tech demos? I guess the NYTimes has some neat stuff that's useful.
Combined with the fonts and font sizes, it's rather hard to enjoy the site.
All of this has nothing to do with the software, which looks really interesting and may be quite successful in the future. But it's worth noting and there's nothing wrong with pointing these things out. ralusek's post should not be so grey.
