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,
6th grader
