Pie Chart Generator

Create pie charts from labeled values and visualize proportional shares.

Last validated: 2026-02-14

Pie Chart Generator turns label-value pairs into a ready-to-use pie chart with percentage slices and a legend. It is useful for quick distribution visuals in status reports, presentations, and internal dashboards when you need a one-page chart instead of opening spreadsheet chart tools. The tool accepts simple line-based input (`Label, Value`), automatically totals values, and shows each segment's share. Invalid lines are skipped with clear feedback so you can fix input quickly. Use it to compare category proportions, communicate composition at a glance, and export the displayed chart view for reports.
