Plotting Points with the Google Maps API

I have a project where the client is looking to be able to create an outline around a specific area on a Google Map and have it clickable with the standard Google Maps info window.

So rather than just a standard point being plotted at a specific lat and long location it would need to create multiple points and a stroke/outline.

Does anyone know if this is even pos开发者_高级运维sible with the Google Maps api?

Thanks.

Sample code:

toggleCommentMode(true);
function toggleCommentMode(isCommentMode){

  if(isCommentMode){
    //$("#map img").css("cursor", "crosshair !important");

    commentModeEventListener = google.maps.event.addListener(FRbase, 'click', commentListener);
  }
  else{
    //$("#map img").css("cursor", "auto !important");
    google.maps.event.removeListener(commentModeEventListener);
  }
}
//}}}

function commentListener(evt){
      var newMarker = new google.maps.Marker({
    position: evt.latLng,
    draggable : true,
    title : "Drag me; Double click to remove",
