Data charts – bar, line, and pie from the same table

MathematicsStatisticsAges 12–13

A single data table (monthly temperatures, top students per class, quarterly revenue…) is drawn as a bar chart, a line graph, or a pie chart. Drag a bar top or a point on the line to edit the values, switch chart types, and see which type fits best: bars for direct comparison, lines for trends over time, and pie slices for percentage shares.
