The Relationship-type layouts cover a range of diagram types, including radial, Venn, and target. These typically depict a connection between two or more sets of things or information.
The SmartArt graphic shown here uses a Converging Radial
layout, in which several elements relate to or affect one central thing.
The Basic Venn
layout, consisting of two or more overlapping circles, shows how areas or concepts overlap and come together at the center intersection.
The Basic Target
layout is used to show containment, gradations, or hierarchical relationships.
