In a Venn diagram sets are represented by shapes; usually circles or ovals. The elements of a set are labelled within the circle. Venn diagrams are especially useful for showing relationships between [..]

1918 (Venn's diagram is from 1904), named for English logician John Venn (1834-1923) of Cambridge, who explained them in the book "Symbolic Logic" (1881).

a diagram using circles or other shapes, to show the relationship between sets.

A diagram in which closed circles represent separately identifiable sets and their logical commonality or distinction by the inclusion, exclusion, or intersection and overlap of the circles. [D03390]

a common diagram used in set theory. Each set is represented as a circle (or other bounded region) and labeled with a capital letter or word. Any member of the set that is specifically denoted (which [..]

A pictorial way of showing the relations among sets or events. The universal set or outcome space is usually drawn as a rectangle; sets are regions within the rectangle. The overlap of the regions cor [..]

Venn diagrams can be useful in organising ideas and notes for essays requiring comparison and contrast of concepts, texts, features etc.

A Venn diagram is often two circles (can be other shapes) that overlap. The overlapping part usually contains information that is pertinent to the labels on both sides of the Venn diagram.

a visual symbolization of components and associations in set algebra. It is a figure wherein circles symbolize the set's components, and the union and intersection between or across the circles s [..]

A graphical device in which closed circles (or ovals) are used to illustrate the logical relationship between sets of data: nonintersecting circles for sets with no elements in common; overlapping cir [..]

a diagram where sets are represented as simple geometric figures (often circles), and overlapping and similar sets are represented by intersections and unions of the figures

A diagram in which overlapping circles are used to show relationships among sets of objects that have certain attributes. Two examples are shown below.

A Venn diagram is a visual means of showing the similarities and differences between two or more items. The similarities are shown in the overlap between two or more circles. Differences are written in the parts of the circles which do not overlap. This example, taken from Wikipedia, shows which upper-case characters are shared by the Greek, Latin [..]

a diagram of overlapping circles drawn within a rectangle used to model relationships among statements

A form of graphic organizer. Commonly used in mathematics and comparisons.

Diagram using circles of different sizes to indicate roles of different organisations and the relationships between them. Used for analysing institutional and social networks. Diagrams
