Create a needle graphic that follows wind direction

I'm building a weather station and would like to add a simple direction needle for the wind. I have a 16 point pole mounted sensor but sometimes, rather than reading the cardinal points, a simple needle would be nice. I've looked at the graphics object and a demo but to me it seems very complicated. Might there be another way? Else I need a little help!
