The universal set is represented by a rectangle.
Subsets of this set are represented by closed curves (often circles). A ⊂ €
Further subsets are represented by a closed curve within a larger closed curve. Q ⊂ P ⊂ €
The intersection of two sets (A & B) is the set of elements that are members of both A & B and is usually shown as a shaded region. A ∩ B
The union of two sets (A & B) is the set of all elements contained in A & B. A ∪ B.

Who invented the Venn diagram?
John Venn, a British logician. And, consequently, it is the Venn diagram, not the venn diagram.
What is venn diagram represents?
Venn diagrams are used to visually represent sets, subsets and which sets or subsets form unions and intersections. For example if there are N employees in a department comprising men, women, smokers, non-smokers, vegetarians, non-vegetarians, then N is the total set and within that there are subsets for example 1) Men who smoke and are vegetarins 2) Women who don't smoke and are non-vegetarians 3) ..... 4) so on Venn diagrams (usually using circles) can depict pictorially how these subsets relate to the main set and other subsets. Once this picture is clealy drawn and understood further mathematical analysis becomes easy.

What are the numbers outside of a venn diagram?
They are the universal set: every number that doesn't fit in the circles in the venn diagram.
What is the Venn diagram of common factors of 28 and 120?
