class anychart.graphics.vector.Circle Improve this Doc

Extends: anychart.graphics.vector.Ellipse

Circle Class. Inherited from Ellipse.
Do not invoke constructor directly. Use anychart.graphics.vector.Stage#circle or anychart.graphics.vector.Layer#circle methods, if you want to create an instance of primitive bound to a stage or a layer.
In case you need an unbound primitive – use anychart.graphics#circle.
