Euler Diagram

CORE DEFINITION
A closed curve is used to represent a set, and the overlapping relationships intuitively show the inclusion, intersection, and mutual exclusion between sets. Scaffolding role: visualization of logical relationships. It presents "who contains whom" and "who intersects with whom" more intuitively than textual descriptions, serving as an auxiliary tool for logical reasoning.
SCAFFOLDING EFFECT
