A pictograph uses large symbols for higher values and small symbols for lower values but the key explains only the number of symbols. What is the main flaw?

Answer and explanation

Correct answer: Changing both size and number makes the value ambiguous

The governing concept is a consistent visual scale and legend. In a pictograph, viewers must know exactly how each symbol represents quantity. If both the number and the physical size of symbols change, it becomes unclear whether value is encoded by count, area, or both. Since the key explains only symbol count, option D is correct. Colour, attractiveness, and background are not the main accuracy issue.
