I have overlapping points at a single location. I need to keep the point locations' integrality so the disperse marker tool is not an option, especially in NYC where slightly moving a marker will place it on the wrong building. Instead, I want to the user to be able to click on a location with multiple points and have the points flare out. Is this possible in AGOL? Its available for Microsoft Silverlight but I am not a Silverlight developer: Working with Clustering.
