How can I get smooth markers (SVG icons) on Google Maps?

Question

I create a marker to place on a Google map:

var compMarker = new google.maps.Marker({
    position: {lat: 33, lng: -118}
    map: map,
    label: {
        text: "10",
        color: "white",
        fontWeight: "bold"
    },
    icon: {
        path: google.maps.SymbolPath.CIRCLE,
        scale: 15,
        fillColor: "#4E90D9",
        fillOpacity: 1,
        strokeWeight: 1
    }
});

This is the result:

As you can see the circle is pretty choppy looking. Is there a way to create a high quality circle?

One option would be to use a custom SVG icon.

icon: {
  url:'data:image/svg+xml;charset=utf-8,' + encodeURIComponent ('<svg viewBox="0 0 220 220" xmlns="http://www.w3.org/2000/svg"><circle cx="110" cy="110" r="100" stroke="black" fill="#4E90D9" fill-opacity="1.0" stroke-width="10" /></svg>'),
  size: new google.maps.Size(200,200),
  scaledSize: new google.maps.Size(32,32),
  anchor: new google.maps.Point(16,16),
  labelOrigin: new google.maps.Point(16,16)
},
