Map visualization limits and issues

I also wish that any "Too Many Values" or other warnings would just go away.  Charts should be smart enough to merge several dots into one if they are too close to each other. 

If the map will only show a sample of the zip codes, we don't know which zip codes are not being mapped so the chart becomes practically useless.  I cannot think of a single scenario where those warnings do anything other than confuse the user who is looking at the chart.

The only time when those warnings are useful is during development.  So maybe the solution is to show the warning during the Edit mode but not during the View mode.
