Multiple Bar Diagram
Since we are required to present the data of two separate entities, the birth and death rate for the respective years, we need a multiple bar diagram to do the job. A bar diagram alone is not enough to represent the two entities. Similarly, birth rate and death rate are unrelated, so we cannot use a component bar diagram to represent them.
