I'd like to produce a map that shows thousands of Markers.
I'm using Markersclusterer to show all these markers.
Yesterday, I received another huge data set (completely different) and I'd like to see its markers with the ones that belong to the previous data set (using MarkerClusterer.
So, I can have different icons for those two data sets.
Can you help me do this?
thanks

Hi I'm already using the MarkerClusterer for one of the dataSets. Now, I have a new dataSet (completely different) and like to display it along with the previous one. So, if for the previous one I have a cluster that has an icon “m1.png” I’d like to have another icon for the same cluster size. I tried to use the MarkerClusterer for both datasets but could not have this duality. –  Ludba Nov 7 '11 at 20:50
