Yo, I heard you like world population data:<p>3D using WebGL -

This is the best population visualization I've ever seen. It's striking that spikes turned out to be so superior to heatmaps. It's possible to intuit the whole dataset at a glance, whereas heatmaps force you to constantly worry about the meaning of every color in relation to every other color.<p>It's obvious in retrospect why spikes are superior: precision. Spikes represent the underlying data much more accurately than colors, especially between datapoints.
Beautifully done<p>ps, noticed you posting in on reddit. I would submit to <a href="http://www.reddit.com/r/visualization" rel="nofollow">http://www.reddit.com/r/visualization</a> as well
Looks great, and generally very smooth for me.<p>When the tooltip changes location it is quite jarring, but I have no good solution for that :) - perhaps only flip the position when you would otherwise obscure the underlying visualisation, rather than when you cross the centre? You could then have the tooltip 'push up' to the edge when you navigate close to it, but when the tooltip would otherwise not be obscuring. There was a submission to HN not too long ago that featured a library that would simplify creating this kind of behaviour, but alas I cannot find it.<p>It took me a while to click on the different years at the bottom, and until I did I wasn't certain what the tooltip data was representing. Probably not a problem, as the discovery was fun, but I guess many might not explore that far.<p>Out of interest, what were your design thought process when choosing a map projection?
Neat!<p>Would be interesting to see predictions through say 2100 or 2200 maybe with different models.<p>IIRC the current predictions are we'll peak around 2050-2060 after which world population will start declining. That assumes that as countries become more affluent they start having less and less children which leads to a population decline. IDK if those models take into account longer lifespans.<p><a href="http://en.wikipedia.org/wiki/Projections_of_population_growth" rel="nofollow">http://en.wikipedia.org/wiki/Projections_of_population_growt...</a>
Very nice! Is it inspired by the Joy Division album cover?<p><a href="http://en.wikipedia.org/wiki/Unknown_Pleasures" rel="nofollow">http://en.wikipedia.org/wiki/Unknown_Pleasures</a>

Pretty cool. Something is wrong in the top left quadrant though, the graph tooltip becomes a little sluggish when it is anchored to the bottom right of the cursor. Might be related to array reversals, etc.
