 For the layout of the buoys, several desirable layout constraints 
 can be enumerated:
 
-    - buoys should not be placed directly on the focus 
-
-    - buoys should be placed close to their anchors

-    - buoys anchored closer to the focus should be larger

-    - the layout should animate continuously when the focus moves

 Because of this, each link has a specific left-right orientation 
 so that a right-end buoy is drawn on the right side of the view
 and a left-end buoy on the left side.
 
 More than two opposing directions could also be used, but

-       - it would limit the layout of a large number of buoys
