What is another name for a pie chart?

• A. Bar graph
• B. Circle graph
• C. Line graph
• D. Trend graph

Answer: (B)

A pie chart is also known as a circle graph because it visually represents data in a circular format, with slices that correspond to portions of a whole. Each slice reflects a category's contribution to the total amount, making it easy to see the relative sizes of parts to a whole at a glance. This format is particularly effective for showing percentages and proportions, which aligns with the circular design of the graph. The other options represent different types of graphical representations. A bar graph uses rectangular bars to show comparisons among categories, a line graph connects data points with lines to indicate trends over time, and a trend graph typically highlights changes or movements over time in a more generalized way but does not convey proportions as effectively as a pie chart.
