Replace boring bars with little pictures — 🍎🍎🍎 for apples sold. Kids love them, newspapers use them, and they hide a sneaky way to lie with size.
A pictograph (or pictogram) uses repeated icons to represent quantities. A key tells you what one icon is worth.
Infographics, children's textbooks, public-facing reports — pictographs make data approachable. But scaling the *icon size* instead of the *count* is a classic distortion.
Pictograph rules
- A key is mandatory — one icon = how many?
- Same-size icons — only the *number* of icons should vary, never their size.
- Partial icons allowed for leftovers (half an icon = half the key value).
Key: 1 star = 20 books. A class read 70 books. How many stars on the pictograph?
How do bad infographics abuse pictographs?
They make one icon twice as tall AND twice as wide to show 'double' — but that quadruples the *area*, so your eye sees a 4× difference. Only the count should change, not the icon's size.
Scaling icon size = lying. If 'twice as much' is shown by an icon with 2× the dimensions, the visual impression is 4× (area). Always count icons, don't eyeball their bigness.
Otto Neurath's 1920s 'Isotype' system pioneered honest pictographs — always more icons for more, never bigger icons. Modern infographics often forget that rule.
- Icons stand for quantities; a key says how much one icon is.
- Vary the count of icons, never their size.
- Partial icons handle remainders.
