Why can comparison become difficult when bars of different widths are used in a graph?

Answer and explanation

Correct answer: Width may also falsely suggest magnitude

The governing concept is proportional and honest data visualization. In a standard bar graph, height or length should communicate the value, while bar widths remain consistent. If widths differ, viewers may also judge the area or visual mass of a bar, making one category seem larger than its numerical value. Thus option D is correct; labels and data do not automatically disappear or become zero.
