Removing a Google maps Circle/shape

Question

I am creating a Circle using the google.maps.Circle() method. This all works fine and dandy, but how can I remove said circle?

My code:

var populationOpt

You need to remove events listeners too, not just hiding the circle, in-fact circle.setMap(null) will just hide the circle

function remove_circle(circle) {
    // remove event listers
    google.maps.event.clearListeners(circle, 'click_handler_name');
    google.maps.event.clearListeners(circle, 'drag_handler_name');
    circle.setRadius(0);
    // if polygon:
    // polygon_shape.setPath([]); 
    circle.setMap(null);
}
