This layout algorithm distributes nodes evenly on the circumference of a circle at positions that result in as few link crossing as possible. Set the Radius property to specify the size of the layout circle. Use SiftingRounds to set the number of fine-tuning crossing-reduction iterations. To apply the layout to a diagram, create a CircularLayout instance, set its members and invoke the ArrangeDiagram method.
