description: Show records related to each other via a many-to-one relationship type in ARC. The many-to-one relationship type uses a lookup relationship to link many records from an object to a single record from another object. In ARC, it shows a lookup field from the child node to the parent node. You can add one-to-many or many-to-many nodes to the child node. Previously, you could create an ARC graph by using only one-to-many or many-to-many relationship types.

# Visualize More Relationships on an ARC Graph

Show records related to each other via a many-to-one relationship type in ARC. The many-to-one relationship type uses a lookup relationship to link many records from an object to a single record from another object. In ARC, it shows a lookup field from the child node to the parent node. You can add one-to-many or many-to-many nodes to the child node. Previously, you could create an ARC graph by using only one-to-many or many-to-many relationship types.

**Where:** This change applies to Lightning Experience in Professional, Enterprise, and Unlimited editions.

**Why:** See connections and related records in a household on an ARC graph by using the Party Relationship Group object and many-to-one relationship type in ARC.

**How:** In Setup, create an ARC relationship graph. On the Properties tab, select relationship type as **Many-to-One**.
