I can draw a simple map using geocode data:

Code:
var map = new nokia.maps.map.Display(document.getElementById("map"),
{components:[ new nokia.maps.map.component.Behavior(),],'zoomLevel': 12,'center':[41.8885694, -87.6355278]});
But I'd like to be able to submit a map request using postal code (zip code) that will return the centroid geocode of that area.
Does the nokia maps API support that?

Thanks,
