In a relation diagram, an arrow drawn from an element in the first set to an element in the second set means that the corresponding ordered pair belongs to the relation. It visually encodes the membership of a specific pair in the subset of the Cartesian product.

Conditions: The diagram shows two sets, typically represented as ovals or circles.; An arrow connects an element from the first set to an element from the second set.

Yes, elements of the sets can be left out of a relation. A relation is a subset of the Cartesian product, so it does not need to include every possible ordered pair.

Conditions: A relation R is defined between sets A and B.; R is a subset of $A \times B$.
