Play map locations as a slideshow
This example autoplays through a series of locations in New York City.
It uses a variable to define a collection of locations, each with a title, description, center, and other properties. Then it defines an automatic playback function and uses that function with flyTo to autoplay through locations on the map and update the descriptive overlay.
