A statistical graphic that combines a bar chart and a line graph: bars show individual values in descending frequency order, while the line shows the cumulative percentage across categories. It carves the 80/20 heuristic visually — the vital few bars that account for the majority of occurrences — enabling rapid identification of which causes dominate a problem set. It persists through spreadsheet software, quality-management tooling, and the visual convention itself taught in Six Sigma and Lean curricula.

Definition
Why it is in scope
A specialized bar-and-line chart that ranks categories by frequency or impact in descending order, with a cumulative percentage line showing the combined contribution of each category. Built on the Pareto principle (the 80/20 rule) to highlight the vital few causes that generate the majority of effects. Persists through quality management practice, statistical software tooling, and the standardized visual convention of ordered bars overlaid with a running-total curve.

A pareto chart is a specific kind of chart that combines descending-frequency bars with a cumulative-percentage line. Per Law 9, 'X is a specific kind of Y' is INSTANCE_OF. A competent speaker would call a pareto chart 'a chart.'

A pareto chart is built for the sake of decision-making: it helps prioritize by showing which factors contribute most to a problem (the 80/20 rule). Per Law 8d, the servant points at the master — the chart serves the decision-making process it supports. Direction: servant (pareto chart) → master (decision-making).
