Bar graphs are best for showing rankings, as it is visually easy to compare the sizes of the bars across categories, particularly when bars are arranged in descending order of value. If we looked at all claims in both the Northern and Eastern Zones and ranked service categories from most to least frequent, Curative Care would be at the top of the list (2097 total claims) and Inpatient Surgery would be at the bottom (6 total claims). For both the Northern and Eastern Zones, the highest ranking service category is Curative Care. For the Northern Zone, the lowest ranking category is Speech Therapy (1 claim), while for the Eastern Zone it is Inpatient Medical and Inpatient Obstetrics (2 claims each).
