You can use this attribute with the following SVG elements:

Example

<svg viewBox="0 0 480 200" xmlns="http://www.w3.org/2000/svg">
  <defs>
    <radialGradient id="gradient1" cx="0.5" cy="0.5" r="0.5"
        fx="0.35" fy="0.35" fr="5%">
      <stop offset="0%" stop-color="white"/>
      <stop offset="100%" stop-color="darkseagreen"/>
    </radialGradient>
    <radialGradient id="gradient2" cx="0.5" cy="0.5" r="0.5"
        fx="0.35" fy="0.35" fr="25%">
      <stop offset="0%" stop-color="white"/>
      <stop offset="100%" stop-color="darkseagreen"/>
    </radialGradient>
  </defs>

  <circle cx="100" cy="100" r="100" fill="url(#gradient1)" />
