This example demonstrates the following features:
- How to handle layer visibilty based on zoom level
- How to show markers in the center of the visible county polygon as the map is panned or zoomed

NOTE: This example implements the use of turf.js for finding the center of a county
polygon. A very nice library for geospatial analysis!
