I would choose a horizontal bar graph for ranking. When looking at claims by service category, Curative Care Visits would be the most frequent (for both zones). Speech Therapy would be the least frequent in the Northern Zone. The least frequent service category would be Inpatient Obstetrics and Inpatient Medical for the Eastern Zone.
