This is similar to wind_rose, but I found that that function did way more than I needed it to.This function:1. takes in angle measurements in earth coordinates (0 degrees is N, 90 degrees is E, 180 degrees is South, 270 deg is West)2. converts those angles into mathematical coordinates3. creates...
