SVGCircleElement: r property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

The r read-only property of the SVGCircleElement interface reflects the r attribute of a <circle> element and by that defines the radius of the circle.

If unspecified, the effect is as if the value is set to 0.

Value

An SVGAnimatedLength representing the radius of the circle.
