          origin: new google.maps.Point(0,0), // origin
          anchor: new google.maps.Point(0, 0), // anchor
          //define the shape
          //define the shape
          shape:{coords:[17,17,18],type:'circle'},
          //set optimized to false otherwise the marker  will be rendered via canvas
          //and is not accessible via CSS
          optimized:false,
          title: 'spot'
  
      };
  
      var marker = new google.maps.Marker({
