How it works
Bars compare amounts by length from one shared baseline; sort them unless the categories have a natural order. A line shows one thing over time. A pie only works for two or three clearly different parts of one whole that add to 100%; percentages from a question that allowed several answers add to more than 100% and must be bars. Below, your values are drawn as sorted bars from zero.
