var center = [-75.343, 39.984];

var units = 'kilometers';
var properties = { foo: 'bar' };

var myCircle = new Circle(center, radius, {
    units: units,
    zoom: 12,
    properties: properties
});

var geojson = myCircle.asGeojson();

// Update circle center
myCircle.updateCenter([0,0]);`

// Update circle zoom
myCircle.updateZoom(10);

// Update circle radius
myCircle.updateRadius(100);
