  *   - autoResize {Boolean} whether the display should listen for window resize events and update automatically (defaults to true)
  *   - groupEdges {Boolean} whether to consider edges with the same origin/destination equivalent for rendering, even if intermediate stop sequence is different (defaults to true)
