Oceans' Warm And Cold Spells
This colorful graph shows when and where the oceans' surface temperatures have seen warm and cold spells in the last 10 years. Mind you that temperature, latitude, longitude and time add up to above the 3D ceiling for instant perception. To cheat to 4D, this graph uses a theory of visual perception and a colorimetric mapping. This trick reveals the spatiotemporal organization of climate data. It is also quite useful to study the brain, epidemics, econometrics, agronomy, demography and many other spatiotemporal datasets.
