SVG fr Attribute

The fr attribute defines the radius of the focal point for the linear gradient.

Syntax:

fr="radius"

Attribute Values:

length: Length at which we want to set the radius.
percentage: Percentage at which we want to set the radius.

We will use the fr attribute for setting the radius of the element.
