Venn Diagrams

The vector stencils library "Venn diagrams" contains 12 templates. Use it for drawing Venn and Euler diagrams.
"A Venn diagram (also called a set diagram or logic diagram) is a diagram that shows all possible logical relations between a finite collection of different sets. Typically overlapping shapes, usually circles, are used, and an area-proportional or scaled Venn diagram is one in which the area of the shape is proportional to the number of elements it contains. These diagrams represent elements as points in the plane, and sets as regions inside curves. An element is in a set S just in case the corresponding point is in the region for S. They are thus a special case of Euler diagrams, which do not necessarily show all relations. Venn diagrams were conceived around 1880 by John Venn. They are used to teach elementary set theory, as well as illustrate simple set relationships in probability, logic, statistics, linguistics and computer science." [Venn diagram. Wikipedia]
The templates example "Design elements - Venn diagrams" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Venn Diagrams solution from the area "What is a Diagram" of ConceptDraw Solution Park.

This Venn diagram sample shows how community elements overlap. It was designed on the base of the figure 1 in the course "eStrategies for Local Governments" from the website of the Southern Rural Development Center (SRDC), the Mississippi State University.
"Ultimately, the goal of this curriculum is to position a community for success as they develop web-based strategies for community and economic development. In support of this goal, the authors use a conceptual model that incorporates four fundamental elements (applications) of a community: government, business, education and community groups (Figure 1). Using the Venn diagram, it shows that each of these elements overlap with another, finally culminating in “Quality of Life” where all four overlap."
