Examples of Euler Diagrams

The following examples show:

(a) The subset relation $T \subseteq S$
(b) Examples of disjoint sets $S \cap T = \O$
(c) The most general case: $S \cap T \ne \varnothing$, $T \nsubseteq S$, $S \nsubseteq T$

The shape of the areas is irrelevant, but usually circles are used.
