A pie chart is specifically designed for showing relative frequencies of different categories in a circular format. It can be useful for visualizing percentages or proportions, but cannot effectively display raw values or trends over time. Histograms and bar charts are better for displaying numerical data, while stem-and-leaf displays are used for showing actual values in a compact format.
