Polygons in Google Maps

In this example you will learn how to add simple polygons in google map.

Here you can view the output of the example and you can also "try it yourself" by clicking on "Live Demo" button given at the bottom.

Syntax

// Construct the polygon.  
  var drawTriangle = new google.maps.Polygon({  
    paths: triangleCoords,  
    strokeColor: '#FF0000',  
    strokeOpacity: 0.8,  
    strokeWeight: 2,  
    fillColor: '#FF0000',  
    fillOpacity: 0.35  
  });  
  drawTriangle.setMap(map);
