Have customer sites shown with the size of the plot being relative to sales in $ / or some other sizing function
Have our internal office sites shown with the size of the plot being relative to the number of employees at that site
Color of customer site would be blue, internal site orange
Perhaps use of shape to indicate the industry of the customer
I do not see a simple / defined way to cleanly put the two different sizing variables on one map at the same time. What I ended up doing was in excel basically manipulating the data to say 5 employees is the equivalent of x amount of $ and having only the one $ field as my sizing option. Thoughts?
