In this example the parcel boundaries layer in the map service is queried when the user is at zoom level 16 or greater.
As the user pans the map, the parcel boundaries layer in the map service is queried again based on the new visible area in the map.
The results are returned to the client and displayed as graphics on the map.
Because the operational layer is rendered client side the client has the ability to access the InfoWindow for each graphic,
to do client side thematic mapping, and listen to the graphic events.
