13 - Creating Variables for Your Map Point Data Layer

The next two tasks will walk you through the process of setting up a map point layer for all airports that have flight alerts. You’ll give your analyst the ability to quickly see the busiest affected airports, and in a future task you’ll build in the ability to view airport details.

You want more, however, than just a static depiction of airports. Let’s set up this point layer so that the airport objects respond to both of our filter lists on the left and to pie chart selections.
