For Scheme's X11 graphics, you can use the DRAW-ARC operation:

(let ((g (make-graphics-device 'X)))
  (graphics-set-coordinate-limits g -1 -1 1 1)
  (graphics-clear g)
  (let ((x 0) (y 0) (r1 .2) (r2 .3) (angle 0) (sweep 240) (fill? #t))
    ;; (graphics-operation g 'DRAW-ARC x y r1 r2 angle sweep fill?)
    (x-graphics/draw-arc g x y r1 r2 angle sweep fill?))
  (graphics-flush g)
  (x-graphics/read-button g)
  (graphics-close g))

If you're using Windows (or, Cthulhu forbid, OS/2), someone who knows
about Windows will have to answer.

(What sixth grade class is using MIT Scheme to draw graphics?  I am
curious to hear!)

It would be very useful to be able to draw filled ellipses on windows.


Thank you,
