This Google Map demonstrates the advantages of using HTML5 canvas to create an overlay for a map.
What impresses me most about the map is how fast the canvas element is drawn on the map. There are a few thousand polygons on this map and they load seamlessly. If you zoom in and out on the map you can really appreciate the speed with which the polygons are displayed.
I think the overlay shows US monthly employment rates.

Thanks for the post. The rendering speed is quite good because we deliver optimized tiles packed in JSON format.
Tiles are also rendered in real-time so there is no need to pre-cache anything.
Here is an article and benchmark we did around that subject.
