Hello all -- I am a Java developer getting into Web 2.0 programming. I'm trying to estimate a client's request, and I am looking for a widget, or pointers to a toolset, or suggestions/ideas for a specific requirement:
They want to be able to see a national map (for example, the USA). Hovering over images of states shows information about the "market" that state is a part of (possibly one or more states). Clicking zooms in on a closeup of the map that encompases that market. Then the zoomed-in map behaves the way with the "districts" in that market, allowing them to see information and zoom even further into that market segment.
Seen anything like this? Any ideas, suggestions, or pointers to websites you have would be very appreciated!
