This interface allows a user to populate data from three pre-selected counties or a county of their choosing. The pre-selected counties are Miami-Dade County in Florida, Washington County in Minnesota, or Falls Church County in Virginia. In order to acquire the data for a county of their choosing, a user can navigate to a team-built tableau dashboard. Either select one of three counties at bottom of page or enter custom data in the fields.

Once the interface is pre-populated with data or a user enters data from their county, a user can experiment with the following data elements by clicking analyze and adjusting the variables available on the sliding scale.
