body: <p>I have drawn polygon for each state over united states map.
  I wish to display a value (text/int) on top of it. I couldnt find any polygon options able to display text on top of polygon. What are the ways to do this?</p>
  
  <pre><code>var poly = new google.maps.Polygon({
                              clickable: true,
                              paths: pts,
                              strokeColor: '#000000',
                              strokeOpacity: 0.3,
                              strokeWeight: 1,
                              fillColor: colour,
                              fillOpacity: 0.8,
                              title: name
                          });
                          polys.push(poly);
                          poly.setMap(map);
