[Leaflet](http://leafletjs.com/) is a Javascript library for drawing maps. Here's an embedded example:

<link rel="stylesheet" href="https://unpkg.com/leaflet@1.0.3/dist/leaflet.css" integrity="sha512-07I2e+7D8p6he1SIM+1twR5TIrhUQn9+I6yjqD53JQjFiMf8EtC93ty0/5vJTZGF8aAocvHYNEDJajGdNx1IsQ==" crossorigin=""/>

<div id="mapid" style="width: 600px; height: 400px;"></div>
<script>

	var mymap = L.map('mapid').setView([51.505, -0.09], 13);

	L.tileLayer('https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token=pk.eyJ1IjoibWFwYm94IiwiYSI6ImNpejY4NXVycTA2emYycXBndHRqcmZ3N3gifQ.rJcFIG214AriISLbB6B5aw', {

	}).addTo(mymap);

	L.marker([51.5, -0.09]).addTo(mymap)
		.bindPopup("<b>Hello world!</b><br />I am a popup.").openPopup();

	L.circle([51.508, -0.11], 500, {
		color: 'red',
		fillColor: '#f03',
		fillOpacity: 0.5
	}).addTo(mymap).bindPopup("I am a circle.");

	L.polygon([
		[51.509, -0.08],
		[51.503, -0.06],
		[51.51, -0.047]
	]).addTo(mymap).bindPopup("I am a polygon.");


	var popup = L.popup();

	function onMapClick(e) {
		popup
			.setLatLng(e.latlng)
			.setContent("You clicked the map at " + e.latlng.toString())
			.openOn(mymap);
	}

	mymap.on('click', onMapClick);

</script>
