Bar Chart Generator

Create bar charts from labeled values and compare categories at a glance.

Last validated: 2026-02-14

Bar Chart Generator converts label-value pairs into a readable horizontal bar chart so you can compare category sizes quickly. It is useful for KPI snapshots, survey summaries, and operational reporting where relative magnitude is easier to read as bars than tables. The tool accepts simple multiline input (`Label, Value`), computes total and percentages, and scales bars against the largest value for immediate visual comparison. Invalid lines are skipped with clear feedback so cleanup is straightforward. Use it when you need fast one-page visuals for documents, slides, or internal updates.
