Physicians from the Community Physician’s Clinic are trying to convince their administration that they need more exam rooms to accommodate their patients. They ask the HIM manager to construct a graph showing the number of patients seen in the last year by the clinic physicians. The categories they wish to have displayed are primary care: 6,798;
medical specialties: 3,423;
surgical specialties: 3,367;
and hospital outpatients: 1,209.
Which type of graph would be appropriate?
