The best type of graph to show rankings with are bar charts, with the categories organized from greatest or most frequent to least. One could possibly consider using a pie chart, as well, depending on one’s goals.
Based on claims in the Northern zone, the most frequent would be Curative Care Visits, and the least would be Speech Therapy.
Based on claims in the Eastern zone, the most frequent would still be Curative Care Visits, but here the least frequent would be tied between Inpatient Medical and Inpatient Obstetrics visits.
