What · honest encoding
The y-axis started at 90, not 0. A truncated axis turns a 4-point gap into a 3x visual difference. For bar charts, length encodes the value, so the baseline must be zero or the bars lie.

Why · right idiom for the task
The task was ranking, but a pie hides rank. Readers can't reliably compare angles, especially across similar slices. Sorted bars put the answer, who's biggest, in the first half-second of reading.
