Keywords
Pie chart - A pie chart (pie graph) is a circular graph where sectors represent different groups proportionally.
Bar chart - A bar chart (bar graph) is a graph consisting of bars visually representing the frequency of objects or groups.
Common misconception
Pie charts but not bar charts can show what proportion of a dataset a particular subgroup represents
You can figure out proportion from a bar chart by comparing the frequency of one subgroup to the total frequency, by adding heights of bars.
