I've done quite a bit of research on the forums on how to include a "simple" Google Map example, and have tried many of them. With all , I seem to end up in the same place as a lot of others end up based on the forum comments - the map never actually comes up. I have a valid API key that I substitute, and still nothing comes up - just a blank VF page. Does anyone have a real working example that I could review and modify?

 I just want to display a set of locations on the map. In my case, location is a custom object with country, state,city and zip (not a standard account record). If I can just get something basic working (i.e. actually see a map), I can then modify it to also set the marker colors based on some properties of the location - it's for a dashboard.

Any help would be greatly appreciated (something in API V3 would be best, but at least an example that works). I thought this was going to be simple...
