  <pre><code>    &lt;image id="Geometry_Point" cx="250.63056092843334" 
  cy="233.0863010581852" r="1" preserveAspectRatio="none" x="235" y="196"
   width="32" height="37" xlink:href="http://icons.iconarchive.com/icons
  /paomedia/small-n-flat/24/map-marker-icon.png" style="opacity: 1" 
  fill="#000000" fill-opacity="1" stroke="#000000" stroke-opacity="1" 
  stroke-width="2" stroke-linecap="round" stroke-linejoin="round"&gt;
  </code></pre>
