Support Air Quality js script?

I am unable to get this up and running on my wordpress site. Any ideas on if this plugin will use this overlay api?

Thanks for your help.

Here is the code:

<div id=’map’ style=’height:380px;’ />
<script src=”https://maps.googleapis.com/maps/api/js”></script&gt;

<script>
var map = new google.maps.Map(document.getElementById(‘map’), {
center: new google.maps.LatLng(51.505, -0.09),
mapTypeId: google.maps.MapTypeId.ROADMAP,
zoom: 11
});

var t = new Date().getTime();
var waqiMapOverlay = new google.maps.ImageMapType({
getTileUrl: function(coord, zoom) {
return ‘http://tiles.aqicn.org/tiles/usepa-aqi/&#8217; + zoom + “/” + coord.x + “/” + coord.y + “.png?token=_TOKEN_ID_”;
},
name: “Air Quality”,
});

map.overlayMapTypes.insertAt(0,waqiMapOverlay);
</script>
