Donut Symbol.

[Jeff Portwine]

I haven't tried this , so it may not work, I've always used filled in 
shapes.. but couldn't you just use a non-filled in circle:

SYMBOL
  NAME "circle"
  TYPE ellipse
  FILLED false
  POINTS
    1 1
  END
END

and then set its size appropriately?   I'm not sure if there is a good way 
to affect the thickness though, other than stacking several of them with 
varying sizes.
