I am on a side project of a condominium, which will have an area on the site that will have the entire condominium area, and inside all lots. Would an outside of me do with Google image or Google maps a way that when the person was passing the mouse or clicking on each lot, would appear a balloon with some information? I found a link that might help you understand Rectangles Google Maps only that would be several rectangles.
Here is the link of the map image
