Google map script has feature if zoom is ‘big’ it groups all pins to the one pin(circle with number of pins, here is example http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/examples/advanced_example.html). How to call this feature on my side? I bring the javascript code which I use to display my map http://jsfiddle.net/LUuwB/ (check javascript section, it is not working there but it is example how I use it).
Thanks
This is not a GoogleMap Features. It’s thirdparty scripts devlopped by users.
You have to go on the Wiki section http://code.google.com/p/google-maps-utility-library-v3/wiki/Libraries to download the released version, with samples and docs.
It’s not hard to use.
