    <div id="map"></div>
    <h3>Code</h3>
    <p>A polygon is created using the <code>H.map.Polygon</code> class, passing in an 
      <code>H.geo.Polygon</code> holding the vertices for the outline and interior parts of the polygon. 
      The look-and-feel of the polygon can be altered by adding the <code>style</code> parameter</p>
