Intermedia and Storyspace are examples of systems in which the links are always bidirectional. Given the simple network below, it is not possible to view the nodes in the order A-B-D-E-C, while this would be possible with bidirectional links. The presentation of bidirectional links requires that both ends of a link can be an anchor, or that links not connected to a specific part of a node can be listed or graphically depicted in some way.
