Data
Pareto Chart Generator ranks categories in descending order and calculates cumulative contribution, helping you identify the few causes that drive most impact. It is useful for defect analysis, support-ticket categorization, and operations improvement programs applying the 80/20 principle. The tool takes simple `Label, Value` input, sorts categories automatically, and displays both individual percentage and cumulative percentage per row. Invalid lines are skipped with clear messages. Use it to prioritize high-impact issues and focus remediation where it matters most.
