This is similar to fillCircle, except it allows you to specify a separate width and height for the circle drawn (which makes it become an ellipse).

.fillEllipse( x, y, width, height, isCentred=false )

Draws a filled ellipse at the x/y location given. If 'isCentred' is true, then x/y is the centre of the ellipse. If it is false, then it refers to the top-left corner.

.fillEllipse( x, y, width, height, xAlign, yAlign )

The same 'fillEllipse' method, but with x and y alignment options. See the article on How Alignment Works for details.
