<desc> element provides an accessible, long-text description of any SVG container element or graphics element .

Text in a  <desc> element is not rendered as part of the graphic. If the element can be described by visible text, it is possible to reference that text with the  aria-describedby attribute. If  aria-describedby is used, it will take precedence over  <desc> .

The hidden text of a  <desc> element can also be concatenated with the visible text of other elements using multiple IDs in an aria-describedby value. In that case, the <desc> element must provide an ID for reference.

<svg viewBox="0 0 10 10" xmlns="http://www.w3.org/2000/svg">
  <circle cx="5" cy="5" r="4">
    <desc>
      I'm a circle and that description is here to
      demonstrate how I can be described, but is it
      really necessary to describe a simple circle
      like me?
    </desc>
  </circle>
