Tree structure

In mathematics and computer science, a tree structure or tree diagram is a way of representing the hierarchical nature of a structure in a graphical form.

Description

It is named a "tree structure" because the classic representation resembles a tree, even though the chart is generally upside down compared to an actual tree, with the "root" at the top and the "leaves" at the bottom.
