You have numbers in your head and want to see them — bar, line, doesn't matter. Paste a few label-value pairs into Chart, pick the shape, and hit draw. The canvas renders it with scaled axes, readable labels, and a clean look. Copy the chart as a PNG or dump the data as CSV if you need to keep working elsewhere. It's not a spreadsheet. It's a sketchpad for data — fast, disposable, and right there in your browser popup.
