There are two variants of both visualisations: one with white background and one with black. IMHO the graphs look better on white and the clouds on black background. I tried to create SVG variants, but they are huge. I also have these figures in 4096 x 3072, but I doubt anyone will need them — if you do, send me a message on and we'll see, they're roughly 10 Mbytes each in PNG format.
