Chart Maker — CSV to bar, line and scatter charts — OnePassApps
Turn local CSV into bar, line or scatter charts. Check an accessible data table and download standalone SVG or PNG without uploading data.
Chart Maker turns a small CSV dataset into a bar, line or scatter chart without an account or an upload. Choose the columns explicitly so the plotted values stay tied to your source. A full accessible data table accompanies the graphic, making it possible to check values even when a long axis label is shortened.
What you can do
- Paste CSV or import a UTF-8 file with unique, non-empty headers and the same number of cells in each row.
- Plot one numeric series, including zero and negative values; scatter charts use numeric X and Y columns.
- Download a self-contained SVG or a 2000 × 1240 PNG after applying the current chart settings.
Limitations
- The tool accepts up to 500 data rows and 1 MB of CSV. It does not aggregate rows, infer missing values, connect to live data or plot multiple series.
- CSV and chart settings remain in memory and disappear when you leave or reload. Save your source and downloaded graphic separately.
Is Chart Maker free, and do I need an account?
Yes, it is free. Chart Maker runs in your browser with no account or payment details, and it never uses OnePassApps credits.
