myHeatmap API Example
Integration with OpenLayers and OpenStreetMap
To use this example, download the OpenLayers source distribution and place these two files in the examples folder.
You can view a live copy of this example here. For more information on the myHeatmap API, check out the docs.
This example also requires an OpenLayers class for myHeatmap overlay layers, hosted here: http://s3.amazonaws.com/myheatmap_api/mHm.js
