Circle

UI Object that displays one or several circles. This object is typically used as an overlay for an image.

If no data source is specified, a single circle will be drawn in the center of the frame. If a data source is defined it will be used to set the center of one or several circles. The positions must be between 0 and 1.

The different circles can be given different colors by specifying a list of colors or a color table for the color attribute.
