The r
attribute defines the radius of a circle.
You can use this attribute with the following SVG elements:
Percentages refer to the normalized diagonal of the current SVG viewport, which is calculated as <width>2 + <height>2 2 .

height: 100%;

circle
For <circle>
, r
defines the radius of the circle and therefor its size. With a value lower or equal to zero the circle won't be drawn at all.
Note: The radius size of a <circle>
can also be defined with the r
geometry property.
For <radialGradient>
, r
defines the radius of the end circle for the radial gradient.
The gradient will be drawn such that the 100% gradient stop is mapped to the perimeter of this end circle. A value of lower or equal to zero will cause the area to be painted as a single color using the color and opacity of the last gradient <stop>
.
