The Three Shires Stone - Nodes and Networks

The Three Shires Stone marks the place where Lancashire, Westmorland and Cumberland used to meet. On the map, three lines come together at a point. That looks like the way they draw networks. The point is a node and the more lines coming into it, the more important it is. In a recent edition of Physics World, there was a report on the use of network analysis to see if Icelandic sagas were history or fiction. Links were drawn between characters. The characters were the nodes and the more lines they got the more important they were. If it looks like real life networks, it could be history rather than fiction. I need to check this but I don't think you can have a node like the Three Shires Stone with only two counties meeting. The interface would be a line. An example would be Caithness and Sutherland.
