Four ways people ask for one.

Same tool, four requests. Every drawing below is a real render.

What you type
Quarterly revenue in $M. Americas 42, 58, 63, 71. EMEA 31, 44, 49, 55. APAC 18, 26, 34, 41. Stack the regions so I can see the total.

The drawing

You bring the numbers. It picks the chart.

Type the figures into the message, or paste a table straight from a spreadsheet. Parts of a whole become a pie, a series over time becomes a line, flows between things become a Sankey.

If you want a different kind, say so. The same numbers are redrawn; nothing is retyped.

How it works

Three steps, no drawing tool to learn.

Describe it

One paragraph is enough to start.

FAQ

Common questions

Can I paste data from Excel or Google Sheets?

Yes. Copy the cells and paste them into the message. Say which column is the label and which are the values if it is not obvious.

Which chart types can it draw?

Fourteen: bar, line, pie, scatter, heatmap, radar, funnel, gauge, candlestick, sunburst, Sankey, treemap, network graph and box plot. For supply and demand or other economics curves, use the supply and demand graph maker.

Can I upload a CSV file?

Not yet. Attachments are photos, PDFs and SVGs. Paste the rows into the message instead.

Can I change colours and labels?

Yes. Say what to change, for example “make APAC grey” or “put the values on the bars”. Every version is kept.
