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

var triangleCoords = [
    {lat: 25.774, lng: -80.190},
    {lat: 18.466, lng: -66.118},
    {lat: 32.321, lng: -64.757}
  ];

  var bermudaTriangle = new google.maps.Polygon({
    paths: triangleCoords,
    strokeColor: '#FF0000',
    strokeOpacity: 0.8,
    strokeWeight: 3,
    fillColor: '#FF0000',
    fillOpacity: 0.35
  });
