One map with 2 Latitudes and 2 Longitudes

[avastani]

Is it possible to have 1 map showing

1. Population of Cities in the country with their own lat and long

2. Another expression with the actual Customer coordinates showing their Sales

This way users can track if Sales occur in high density or low density areas.

I presume this would be a good visual, but don't know if it is doable with the current limitations of mapping providers.
