Examples of Euler Diagrams
The following examples show:
- $(\text a)$ The subset relation $T \subseteq S$
- $(\text b)$ Examples of disjoint sets $S \cap T = \O$
- $(\text c)$ The most general case: $S \cap T \ne \O$, $T \nsubseteq S$, $S \nsubseteq T$
The shape of the areas is irrelevant, but usually circles are used.
