CircularSeries<T, D> class

This class holds the property of circular series.

To render the Circlular chart, create an instance of PieSeries or DoughnutSeries or RadialBarSeries, and add it to the series collection property of SfCircularChart. You can use the radius property to change the diameter of the circular chart for the plot area. Also, explode the circular chart segment by enabling the explode property.

Provide the options of stroke width, stroke color, opacity, and point color mapper to customize the appearance.
