Pictogram Maker — Free Icon Charts (Isotype)

In short: the Pictogram Maker turns values into rows of dots — one full dot per 10 units, with a lighter dot for a large remainder — the isotype style invented for public information.

When the audience is young, busy or reading in a second language, counting symbols beats reading axes. Pictograms are the original data visualisation for everyone.

Private by design: everything in this tool happens 100% in your browser with JavaScript. Your data, photos and designs are never uploaded to a server, never stored and never seen by us - close the tab and everything is gone.

How to use the Pictogram Chart Maker

  1. Type your labels and numbers into the grid, or paste CSV into the box below the chart and press Apply CSV.
  2. Adjust the title, legend and per-series colours until the chart reads clearly at a glance.
  3. Press Download chart as PNG and drop the image into your document, slides or post. Use Copy my data as CSV to save your figures for later.

How it works

Full dots = value ÷ 10 (rounded down). A remainder of 2 or more units shows as a pale partial dot, and the exact value always prints beside the label, so the picture never replaces the number. The chart is drawn by hand on an HTML canvas by Loona’s shared chart engine — no chart library and no server. Everything is computed locally, so your numbers never leave your device.

Worked example

A primary school charts how students travel to school. Children count the dots themselves — the chart becomes the lesson.

Frequently Asked Questions

What does one dot mean?

Ten units, stated under the chart. Values print beside each label for exactness.

Why dots and not icons?

Neutral dots keep the chart honest and fast at any size; the counting idea — not the picture — is what makes a pictogram work.

Which series is used?

The first series, one row per label.

Is it free?

Yes — free and private, like every Loona chart.
