I wish to create a heatmap like this one at http://www.trulia.com/local/san-francisco-ca/tiles:1|points:1_crime
With the number changes at different zoom level - the number can appear in a mouse-hover window instead of directly showing on the map.
Any idea how to make this with Leaflet map?
I have a csv file with three columns:
lat lng count
Any tips how to easily load it for Leaflet.markercluster?
