Pareto Chart Generator

Create Pareto charts with sorted categories and cumulative percentages.

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.
