Pie charts are best for showing percentage increases or decreases over time; however, they don’t do well with large numbers since it’s difficult to see how much one slice represents in relation to another.
A bar chart is a rectangular chart that illustrates numerical data by displaying the height of bars, which are typically horizontal but may be vertical.
