This figure shows our 2D rule visualizer.
In this example, we chose two numeric attributes, "Age" and "Glucose",
and divided them into 16x16 (64) cells. For each cell, brightness
represents the number of people, and redness expresses the ratio of
diabetes diseased patients.
The region enclosed by light-blue lines is the maximized confidence
region with a given minimum support threshold (threshold of the size
of the region).
By moving the slider, the minimum support threshold can be
controlled. As you move the slider, you can see changes of the
maximized regions.
