Description of the <circle> element

The SVG <circle> element creates circles, based on a center point and a radius. The coordinates of the circle's center are specified by the cx and cy attributes. And the radius of the circle is specified by the r attribute.

Example of the SVG <circle> element:

<!DOCTYPE html>
    <title>Title of the document</title>
    <svg height="300" width="300">
      <circle cx="150" cy="150" r="100" stroke="grey" stroke-width="5" fill="purple" />
      Sorry, inline SVG isn't supported by your browser.  

Let’s explain the code above:

  • The cx and cy attributes specify the x and y coordinates of the circle’s center. In the cases where the cx and cy attributes are omitted, the center of the circle is set to (0,0).
  • The r attribute is used to specify the radius of the circle.


The SVG <circle> element also supports the Global Attributes and Event Attributes.

Attribute Description
cx The x-axis coordinate of the circle’s center.
cy The y-axis coordinate of the circle’s center.
r The radius of the circle. A value that is lower or equal to zero will disable the rendering of the circle.
pathlength This attribute specifies the total length for the path, in user units.
