Perhaps you mean the Venn diagram.
The four types of mapping diagrams are: Function Mapping Diagrams: These illustrate the relationship between inputs and outputs in a function, typically showing how each input is uniquely paired with one output. Relation Mapping Diagrams: These represent relationships between sets where an input can be related to one or more outputs, highlighting non-function relationships. Set Mapping Diagrams: These visualize the connections between different sets, showing how elements from one set relate to elements in another. Venn Diagrams: A specific type of set mapping, Venn diagrams depict the relationships and intersections between different sets, helping to visualize common and unique elements.
a Venn diagram consists of two overlapping circles, and is generally used as a compare and contrast diagram. a diagram in general is just a way to show information. in short, they are not the same thing, a venn diagram is a type of diagram.
