title: Heatmap in V3 without Fusion Tables?
body: <p>The new FusionTablesLayer in Google Maps API version 3 has an option to display as a heatmap instead of points. <a href="http://gmaps-samples-v3.googlecode.com/svn/trunk/fusiontables/beaches_heatmap.html" rel="nofollow noreferrer">Here's the example</a>. Is there a way to get the heat map display without using Fusion Tables (but still using the Google Maps API)? I already have my data in my own PostgreSQL/Postgis database. Having Google do the heatmap a preferred alternative to implementing my own tile server.</p>
