How do I format my data?

Use CSV lines in the format Name,Value per line (example: Math,80). For advanced multi-series provide semicolon-separated values (example: RegionA,10;20;30).

Can I export charts for print?

Yes — export as PNG for images or PDF for print-ready A4 landscape pages; you can also download the parsed CSV data.

Is my data uploaded or stored?

No. All parsing, rendering and exports run inside your browser — nothing is uploaded to a server.

Which chart types are supported?

Bar, line and pie charts are supported. For multi-series use bar or line charts; pie charts work with a single series.

Can I customize series colors?

Yes — the UI provides a primary color and per-series color pickers for multi-series charts.

Frequently asked questions

How should I format my CSV?

For single-series charts use: Label,Value. For multi-series: Label,v1;v2;v3 — ensure each label line has the same number of series values.

What export quality can I expect?

PNG exports use the canvas resolution; PDF embeds the canvas into an A4 landscape page. For higher-res prints increase your browser zoom or canvas dimensions before export.

Is the tool free and private?

Yes — the tool runs in the browser only, performs no server uploads, and is free to use. No user accounts are required.

How do I use multi-series data?

Provide values separated by semicolons, e.g. Jan,10;20;15. Then enter series names like Product A,Product B,Product C and click Generate.

Can I embed the chart on other pages?

The app is a front-end tool. For embedding, export the chart as PNG and insert the image in articles, or host your own copy of the app and link to it.
