Limitations — read this before you rely on it
Charts are drawn on an HTML canvas with no external library, so styling is intentionally simple: no axis gridlines beyond the baseline, no legend beyond the pie labels, and long labels may clip on narrow charts. Data is limited to the text you paste; there is no spreadsheet import.
Frequently asked questions

Yes for bar and line charts (bars scale from the minimum); pie charts need non-negative values that sum meaningfully.
No — the chart is drawn in your browser and never leaves your device.
Each slice is rounded to one decimal, so rounded slices can total 99.9% or 100.1%.
