How to stylize a circle?

问题:

It's possible to stylize polylines with dashes or dots by using icon as described in Styling a Google Maps v3 Polyline with Dashes or Dots?.

But I didn't find how to stylize circles.
Any suggestions, reference please.

One option, draw a circle with a google.maps.Polyline and stylize the polyline:

  var donut = new google.maps.Polyline({                  path: drawCircle(new google.maps.LatLng(-33.9,151.2), 100, 1),                  strokeOpacity: 0,                  icons: [{                    icon: lineSymbol,                    offset: '0',                    repeat: '20px'                  }],                  strokeWeight: 2,                  fillColor: "#FF0000",                  fillOpacity: 0.35      });      donut.setMap(map);
