Network Display provides a window to view the model network. States, connections and directions of information flow can be observed, and causes of errors found. As complexity grows, the textual form loses the ability to bring together at one point all the influences from different parts of the network, whereas a graphical representation shows these influences while concealing their precise details. Some actions, such as setting diode behaviour in a link or changing the existence value for a constant, are only possible from the Network Display.
