Visualization of Associations
The figure below is a visualization of a set of association rules with
exactly one item in the head and one in the body. (The item labels are not
shown in this picture). The different colors denote difference confidence
levels. The user could have the color dentoe the support instead.
This figure runs off a similar data set, but the height of the bars denotes
the confidence, while the color denotes the support. The vertical plane
can be moved by the user to partially hide all rules whose confidence is
below a certain threshold. The user can also have the height show the
support and the color the confidence.
This figure visualizes rules with two items in the body and one in the
head. You can click on the image to get a full-size version. The bottom
plane shows 2-item rules as boxes, similar to the first figure. The center
boxes show 3-item rules. Users can "fly" through this space to explore
clusters, or click on a box to highlight all rules containing any of the
items in that box.
