What data can I paste?

CSV, TSV or a table copied straight from a spreadsheet — the first row is treated as headers and numeric columns are detected automatically.

Are the colors accessible?

Yes — the palette is validated for color-vision deficiency and contrast in both themes, and every chart carries a legend, direct labels and hover values.

What export formats are there?

Crisp SVG (scales to any size) and 2× PNG for pasting into documents and slides.
