Common Pitfalls
Translation Traps (for Russian speakers)
- Не путать с 'картой' (map) или 'диаграммой' (diagram/chart). Картограмма — это конкретный гибрид того и другого.
- Не переводить дословно как 'картограмма' (хотя это прямой заимствованный термин в русском научном языке, в быту он почти не используется).
- В русском для неспециалиста ближе описательный перевод: 'статистическая карта' или 'схематическая карта, искажающая площадь для показа данных'.
Common Mistakes
- Confusing a cartogram with a choropleth map (which uses colour shading on a true-scale map).
- Pronouncing it as 'car-toe-gram'. The first syllable is 'car-'.
- Using it to refer to any map with data on it.
- Spelling: 'cartagram', 'chartogram'.

An infographic is a broad term for any visual representation of information. A cartogram is a specific type of infographic that uses a map as its base and distorts it based on data.
No. The term has been used in English since the late 19th century, originating from the French 'cartogramme', itself from the Greek 'chartēs' (sheet of paper/papyrus) and 'gramma' (something written/drawn).
