title: Tableau 'map' type messing up sized visualization
body: <p>I am making a map chart in Tableau where I have lat and long coordinates and I want the dots showing these locations to be bigger or smaller based on the number of mosquitos caught in the specific traps (marked by the lat and lon coordinates). This works perfectly as long as I use the 'automatic' chart type:

  However if I switch to the 'map' type, the dots do not represent the sizes anymore. Notice that I did not change ANYTHING else but the chart type:

  Could someone explain why this happens and how to 'fix' it?</p>
