Graphviz would be my solution of choice for this situation.

Your data above would be written as the following in 'dot' notation:

digraph Connections {
  A -> B
  A -> C
  B -> C
}

You run that through dot:

$  dot -Tps data.dot -o data.ps
$  psd2pdf data.ps

and you get http://circle.homeip.net/~lance/data.pdf
