Creating Heat Maps with the Google Maps API
HeatmapTool is a service for easily creating heat maps with the Google Maps API.
To create a heat map with HeatmapTool the user simply needs a comma separated values file (CSV) of their location data. The tool includes a number of options to customise the colors used, the size of the spot radius and the opacity of the heat map overlay.
The free version of HeatmapTool allows the user to create heat maps with up to 100 data points and allows for 500 hits per day.
