Place ID Geocoder

The Place ID Geocoder sample uses the Place Autocomplete widget to allow a user to search for a place. After it retrieves the place details, the sample marks the place on the map, then reverse geocodes the place ID to get the place's geographic coordinates. Finally, the sample displays an info window that contains details about the place (name, place ID, and formatted address).
