ribbon.startAngle()

ribbon.startAngle([angle])

If angle is specified, sets the start angle accessor to the specified function and returns this ribbon generator. If angle is not specified, returns the current start angle accessor, which defaults to:

function startAngle(d) {
  return d.startAngle;
}

The angle is specified in radians, with 0 at -y (12 o’clock) and positive angles proceeding clockwise.
