Now the strongest paths have to be identified. To help visualize the strongest paths, the set of pairwise preferences is depicted in the diagram on the right in the form of a directed graph. An arrow from the node representing a candidate X to the one representing a candidate Y is labelled with dY. To avoid cluttering the diagram, an arrow has only been drawn from X to Y when dY > dX (i.e. the table cells with light green background), omitting the one in the opposite direction (the table cells with light red background).
