I’m using Google web toolkit for some project mapping seismic activity of some land area. The request from users is to create a map which marked points. When user will click on some point, more detailed information is shown.
So, I need to be able to draw some particular areas on a common image. Areas should be dynamically drawn (size and color based on last monitoring figures), and active: when user hover a mouse or click to the area, more detailed information is shown.
Please see the example of image:

I tried many ways how to draw dynamically or overlay image, and to bind handlers, but nothing was successful. Any ideas please?

Not sure if all of the mentioned projects suit your needs but I guess they’ll help as a starting point.
