I am trying to render a GeoJSON polygon from a variable called data using the Google Javascript API. The overlay does not render properly and I do not know why. Can somebody please show me how to render a polygon on the map?

var x=new google.maps.LatLng(40.75597,-73.974228);
function initialize() {
var data = { "type" : "Polygon", "coordinates" : [ [ [ -73.974228, 40.75597 ], [ -73.983841, 40.742931 ], [ -74.008133, 40.75307500000001 ], [ -73.998131, 40.765915 ], [ -73.974228, 40.75597 ] ] ] }
var mapProp = {
center:x,
zoom:4,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map=new google.maps.Map(document.getElementById("googleMap"),mapProp);
map.data.loadGeoJson(data);
}
google.maps.event.addDomListener(window, 'load', initialize);

I get a javascript error with your code: Uncaught InvalidValueError: not a Feature or FeatureCollection. Make your polygon a "Feature":
var data = {
type: "Feature",
geometry: {
"type": "Polygon",
"coordinates": [
[
[-73.974228, 40.75597],
[-73.983841, 40.742931],
[-74.008133, 40.75307500000001],
[-73.998131, 40.765915],
[-73.974228, 40.75597]
]
]
}
};

code snippet:
function initialize() {
var data = {
type: "Feature",
geometry: {
"type": "Polygon",
"coordinates": [
[
[-73.974228, 40.75597],
[-73.983841, 40.742931],
[-74.008133, 40.75307500000001],
[-73.998131, 40.765915],
[-73.974228, 40.75597]
]
]
}
};
var mapProp = {
center: new google.maps.LatLng(40.75597, -73.974228),
zoom: 12,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("googleMap"), mapProp);
map.data.addGeoJson(data);
}
google.maps.event.addDomListener(window, 'load', initialize);html, body, #googleMap {
width: 100%;
height: 100%;
