Nokia Maps API supported web browser (basically any modern browser should do).
Example code
This example will start panning the map to the right, then after a moment changes direction to the left and continues forever(?) ;) Unless you stop it by pressing the button and clearing the timer and interval settings. Remember to add in your own AppId and Token to get it to work.
