About this chart generator
Enter one label,value pair per line and choose a bar, line or pie chart to preview it instantly: bar and line charts come with axes, ticks and horizontal grid lines, while the pie chart draws sectors proportional to each value with percentage labels. Charts are hand-rendered on Canvas with devicePixelRatio scaling, so the exported PNG stays sharp on high-resolution screens.
A six-color palette cycles across your rows, and the legend lists every label with its value (plus percentage for pie charts) — no configuration needed. Hit Download PNG to save the current chart for reports, slides or chats. Everything is drawn locally; your data never leaves the browser.
