A graph scale begins from the middle but this is not made clear. What is the risk?
A graph with a truncated scale can visually exaggerate differences. For example, if the vertical axis begins at 90 instead of 0, values of 92 and 96 may appear far apart even though their actual difference is only 4 units. Therefore, option D is correct. The scale does not erase data or alter the title; the risk is misleading visual interpretation.
