I have a requirement wherein i would need to use Qlikmaps for which i happen to use polygons variant which gives the desired output but as it consumes boundary data and not latitude and longitude information I am unable to use it against few customized locations which is made use of in our projects. Hence would want to know if there are any extensions which would consume latitude- longitude data to provide a heat map kind of display across geographical area, our area of interest would be North America across which we would like to show the data points.
