The IlvSimpleCompositeChartRenderer is the base class for simple composite renderers.
An IlvSimpleCompositeChartRenderer creates one child renderer per
data set. The type of the child renderers is determined by the
createChild() factory method. This method
should be overridden by subclasses to return an instance of the wanted class.
CSS example:
This class cannot be instantiated because it is an abstract class.
