I wrote a program that takes a connection list such as
[
(1, n [b 2, b 3, b 4]),
(2, n []),
(3, n [b 5, b 6, b 7]),
(4, n []),
(5, n []),
(6, n []),
(7, n [b 8, b 9, a 1]),
(8, n []),
(9, n [])
]
and generates an image such as the one attached.
Trouble is... it's not a very good graphic, is it? :-/
