GUI tree

A GUI tree is a type of computer program that is used for organizing information. It is made up of a series of “nodes,” which each represent a piece of information. For example, you might have a node that says “Animals” and another node that says “Cats.” The Cats node is a branch of the Animals node, just like how cats are a type of animal. If you clicked on the Cats node, you would see even more branches that are about cats. Each one of those branches would have their own nodes which can have more information about cats. GUI trees are helpful for organizing information in a way that is easy to find and understand.
