What issue can arise when a chart has too many categories?

• A. The chart becomes faster.
• B. It automatically repairs itself.
• C. The chart can become crowded and difficult to read.
• D. It becomes unreadable due to format.

Answer: (C)

Too many categories in a chart makes the visualization crowded and hard to read. When there are lots of categories, the slices or bars become very small, labels can overlap or spill into the legend, and color differences become too subtle to distinguish. All of this makes it difficult to compare values at a glance or identify which categories drive the results. To keep charts clear, it’s best to limit the number of categories or combine smaller ones into an “Other” group, or switch to a different chart type like a horizontal bar chart or a table that presents the data clearly.
