Venn Diagram (Venn) Analysis

A Venn diagram may also be called a primary diagram, set diagram or logic diagram. It is a diagram that shows all possible logical relations between a finite collection of different sets. These diagrams depict elements as points in the plane, and sets as regions inside closed curves. A Venn diagram consists of multiple overlapping closed curves, usually circles, each representing a set. The points inside a curve labelled S represent elements of the set S, while points outside the boundary represent elements not in the set S. This lends itself to intuitive visualizations; for example, the set of all elements that are members of both sets S and T, denoted S ∩ T and read "the intersection of S and T", is represented visually by the area of overlap of the regions S and T.

Overall solutions

CD ComputaBio's venn diagram can be used to count the number of common and unique OTUs in multiple samples, and can more intuitively show the similarity and overlap of the OTU number composition of environmental samples. Normally, an OTU sample sheet with a similar level of 97% is used for analysis.

In the Venn Diagram, different colors represent different samples. If the area where two circles of different colors overlap is marked with the number 100, it means that both samples are sequenced into the same OTU, and there are 100 such OTUs. The number of samples in the picture is generally 2~5.
