Oops - forgot the CIRCLE function
(from Dick Jackson <djackson@dfanning.com>)

FUNCTION CIRCLE, xcenter, ycenter, radius, nPts

IF N_Elements(nPts) EQ 0 THEN nPts = 100
points = (2 * !PI / (nPts-1)) * FIndGen(nPts)
x = xcenter + radius * Cos(points)
y = ycenter + radius * Sin(points)
RETURN, Transpose([[x],[y]])

END
