Dot density map

This is an attempt at a slightly D3-ish way of drawing a dot density map on a canvas element. In short, each polygon is drawn (invisibly) with a unique color, then random points are thrown at polygon bounding boxes and the pixel color is used for a point-in-polygon test. This example draws one dot for every 2 people in central Boston census blocks, for a total of approximately 132,000 dots.
