Come look at my new project, nanocubes, in collaboration with my co-workers Jim Klosowski and Lauro Lins. Nanocubes are in-memory datacubes for spatiotemporal data. They enable super-fast interactive, exploratory visualizations of large datasets. The live demos on the site show up to 200 million data points.
There’s a forthcoming paper describing the work, and the software will be open-sourced sooner rather than later. Until then, have fun with the demos! Feedback is more than appreciated.
