ZH: Really Fast Heatmap

ZH is really fast both in terms of the speed in which heatmap is generated and of the performance when displayed by a modern browser. This is because it draws the map using a bitmap format with each pixel representing a square in the heatmap. This bitmap is then encoded as base64 and embedded in an <image> tag in an SVG.

You browser won't break a sweat with a 10-million square heatmap.
