I'm looking for a google map example that has XML file for the source which clusters the map icons and allows the user to filter the items on the map by category using checkboxes. If possible I would like to have a drop down box for a specific year or all years. When the user makes a change to the checkbox or drop down, the map clusters meted to be updated.
There are plenty of samples on clustering of map icons, and I've used a filter on the map, but I have not used both together. I am hoping someone out there has a sample.
