Meaning and Definition
A type of diagram that shows data using sectors of a circle to represent proportions of a whole.
Also known as a pie chart; a circular statistical graphic divided into slices to illustrate numerical proportion, where each slice's arc length is proportional to the quantity it represents. In discrete mathematics and graph theory, 'circle graph' can also refer to the intersection graph of chords of a circle.
Dialectal Variation
British vs American Usage
Differences
The primary term in British English for the data visualisation is 'pie chart'. 'Circle graph' is understood but less common. In American educational contexts (e.g., school textbooks), 'circle graph' is frequently used interchangeably with 'pie chart'. The mathematical graph theory meaning is consistent in both varieties.
Connotations
In BrE, 'circle graph' might sound like a less technical or more child-friendly synonym for 'pie chart'. In AmE, it is a standard, neutral term in educational materials.
Frequency
In data visualisation contexts: 'Pie chart' is significantly more frequent in BrE. 'Circle graph' has moderate frequency in AmE educational texts but is still less common than 'pie chart' in professional AmE.

Meaning in Context
Business
Used in reports and presentations to show market share, budget allocation, or survey results (e.g., 'The circle graph on slide 12 breaks down our departmental costs.').
Academic
Common in social sciences, education, and introductory statistics to teach proportional reasoning. In mathematics, refers to the chord intersection graph.
Everyday
Used when discussing simple data representation, often in school projects or news infographics (e.g., 'I made a circle graph for my science fair project.').
Technical
In graph theory: a graph whose vertices can be represented as chords on a circle, with edges between intersecting chords.
Watch out
Common Mistakes When Using “circle graph”
- Using 'circle graph' in formal business reports where 'pie chart' is expected (especially in BrE).
- Confusing the data visualisation term with the mathematical graph theory term due to lack of context.
- Incorrectly calculating percentages so that the sectors do not total 100%.
FAQ
Frequently Asked Questions
In the context of data visualisation, yes, they are synonymous. 'Pie chart' is the more universally recognised term, especially in business and professional settings.
Avoid using circle graphs/pie charts when you have many categories (more than 5-6), when precise comparison between similar-sized segments is needed, or when the data doesn't represent parts of a whole (100%). Use a bar chart instead.
In discrete mathematics and computer science, a circle graph is a type of graph that represents the intersection relationships of chords drawn on a circle.
In British English: /ˈsɜːkl ɡrɑːf/. In American English: /ˈsɜrkl ɡræf/. The main difference is in the vowel of 'graph' (/ɑː/ vs. /æ/).
A type of diagram that shows data using sectors of a circle to represent proportions of a whole.
Circle graph is usually formal, technical, academic in register.
Learning
Memory Aids
Mnemonic
Think of slicing a circular PIE to show how the GRAPH divides the whole into parts. Circle = the shape, Graph = the data picture.
Conceptual Metaphor
A WHOLE IS A CIRCLE; PARTS ARE SLICES/PORTIONS.
