ArulesViz plots

So far you have plotted scatterplots. They allow you to have an overview of rules according to the various metrics (confidence, support and lift). However, you may want to have a different type of visualization and explore the set of other plots that are available in the ArulesViz package. These plots enable you to have a better understanding of the set of extracted rules. The rules rules_online are saved in the workspace.
