"Add a kernel function on the map (plot the density of pins on the map).  Ability to specify a kernel density function used to generate heatmaps"

Give the user a better visual experience of heat map data at closer zoom levels by using more colors and "heating" visuals like in zoom levels 9 and above. Now points that are close/overlapping appear as red area on close zoom levels."

Yes, I'd really like to see that feature - it will solve mapping huge data sets as points (by rasterising them).

And control how "hot" each point is.  If I have sparse data each one needs to be hotter to show up properly.

It looks like Google Maps has added this ability via the visualization library (https://developers.google.com/maps/documentation/javascript/reference#WeightedLocation). Hopefully, Fusion Tables will also implement this feature soon!

Well, since it is not using the the Fusion technology (pre-rendered tiled images), performance will be an issue :-|

As a prototype API though this is exactly what I'd like to see in the Fusion tables.
