Chart Maker

100% client-side. Your data never leaves this page. Verify: DevTools → Network.

Data (CSV / TSV)

Paste a small table — the first column is the category labels, each remaining column is a numeric series — and get a bar, line or pie chart rendered as crisp SVG. Bar and line support multiple series; pie uses the first series. Export the result as a scalable SVG or a 2× PNG for slides and docs.

The chart is drawn with hand-written SVG (no charting library to load) and everything happens in your browser — your data is never uploaded.
