    </div>
    <p>This example shows visualization of animated DOM markers on a map. Markers change their positions to random
       geo coordinates generated within radius of 450 km from the map's center.
    </p>
    <div id="map"></div>
    <h3>Code</h3>
    <p>
      DOM markers with SVG icon are placed around the Europe. Each DOM marker then periodicaly changes its position using
      <code>setGeometry()</code> method to randomly generated geo coordinate with an animation. To calculate random
      geo coordinate within specified radius, <code>H.geo.Point#walk()</code> method is used.
      The animation effect is achieved with help of custom <code>ease()</code> function which is called
      within <code>updateMarkerPositions()</code> function each interval loop.
