Chart Maker
Paste rows in the form «label, number» and the chart appears as you type.
How to use
Pick a chart type and paste your data: one row per line, a label, a comma and a number. Labels may contain commas — the last one is treated as the separator. The finished chart downloads as a PNG for a presentation, or as an SVG that stays sharp at any size.
Choose the type by the job, not by taste. Bars compare quantities against each other. A line shows change over time. A pie divides a whole into parts — and only works when the parts genuinely add up to a meaningful whole and there are not many of them.
FAQ
When is a pie chart the wrong choice?
When there are more than about seven slices — the eye stops being able to compare them and the chart becomes a coloured blob. It is also wrong when the values do not form a whole: sales across different years belong in bars, not slices.
Are the colours picked at random?
No. The palette is validated for colour-blind separation and for contrast against the background, in both light and dark themes. Colour is also never the only key: slices carry labels and a legend, bars carry their values.
Which download format should I choose?
PNG is an ordinary image that pastes anywhere. SVG is vector: it stays sharp at any magnification and is the right choice for print or further editing.
Is my data sent anywhere?
No. The chart is drawn in your browser and the numbers stay with you.
