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.

Document Object Model

The Document Object Model uses a tree structure.
