Few months ago I have been researching with some colleagues new ways of visualizing data. Infovis has been a theme I've always been interested in because it is a field where rich interactions can be of real help on a functional level. The most worthy piece I did in the past is probably Tagged Colors. One of the aims of the research was to that the charts should be able to manage time browsing, so I thought straight away how common charts could handle it. I am not a big fan of pie charts but when imagining it in a 3D environment, it got more interesting. Of course I had to show to the others what I had in mind and for this reason I picked a tool I was pretty familiar with, Processsing. Processing has been created for rapid prototyping and it is especially useful if you need simple drawing API (lines, points, polygons), of course you can do much more complex things with it.
Below you can see the result after few hours with Processing and Eclipse.
