Question

Write down the usage of a pie chart.

Answer 1

• Part-to-Whole Relationship: It is strictly used to display a single data series to show how individual components or proportions contribute to a cumulative total (where the complete circle equals 100%).
• Proportional Representation: It represents data values visually as slices of a circle, making it easy to see the relative size of each category at a glance (such as illustrating market share, company budget allocations, or expenditure breakdowns).
• Limited Categories: It is ideally used for a small dataset containing no more than five to seven categories to avoid visual clutter and ensure the data labels remain clean and readable.
