Client-side projection

This sample demonstrates how the geometries of client side features, whether added as graphics to the MapView or as a GeoJSONLayer, are automatically projected using the client-side projection module.

The MapView's spatialReference is switched on the fly to a projected spatial reference selected by the user.
