Hierarchy Tree
Definition
A hierarchy tree is a graphical representation that illustrates the hierarchical relationship between different elements or entities. It organizes them into levels or layers based on their parent-child relationships.
Analogy
Imagine you have folders on your computer organized into subfolders within subfolders. The top-level folder represents the root node, and each subsequent level represents child nodes branching out from their parent nodes. This hierarchical structure resembles a hierarchy tree.
