There isn't a pre-cooked function.

A possible solution is to write a script that calculates the circle
(approximated with an n-edge polygon) and produces a polygon or
linestring directive usable by kaXmlOverlay.


Another solution is to reuse part of the code on kaXmlOverlay
(particularly the methods kaXmlSymbol.prototype.draw_*) to draw the
circle with the calculated radius: in this case you have to provide
the handling for scale changes.
