Figure 6-11: This shows all the products purchased with the extension
cord (in green).
However, because it is already known that all items are connected to the
extension cord, it is no longer necessary to display the extension cord node
and its associated edges—all those edges are obscuring further analysis.
Selecting the extension cord node and deleting it makes the rest of the graph
somewhat easier to decipher, as shown in Figure 6-12 . In this particular
graph, another product also seems to act as a bridge between the left and
right clusters—it is a power strip.
