Frequently asked questions

Is my data uploaded to a server?

No — all processing happens in your browser. Your CSV data and generated charts never leave your device.

Which chart types are supported?

Bar, Line, Pie, and Doughnut charts are supported. More types may be added in future.

Can I plot multiple columns?

Currently one Y-axis column is supported per chart. To compare multiple series, generate separate charts.

What format is the download?

Charts are downloaded as PNG images at the canvas resolution — suitable for presentations and reports.

Does it work on large CSV files?

Yes, but charts with thousands of data points can become hard to read. Consider filtering your CSV first for best results.

Can I customise colours?

Yes — choose from five colour schemes: Blue, Green, Warm, Cool, and Colourful. Each scheme cycles through five distinct colours.
