What kind of graph identifies a hierarchy?

Answer 1

A hierarchical structure is typically represented using a tree graph or dendrogram. In a tree graph, nodes represent entities, and edges indicate relationships, with a single root node at the top and branches leading to subordinate nodes. This format effectively displays levels of authority, categories, or classifications, making it easy to visualize the hierarchy. Dendrograms are often used in clustering and taxonomy to show relationships and groupings among data points in a hierarchical manner.
