A tree structure (i.e. a rooted, connected acyclic graph) is often used in programming. It's often helpful to visually examine such a structure. There are many ways to represent trees to a reader, such as indented text (à la unix <code>tree</code> command), nested HTML tables, hierarchical GUI widgets, 2D or 3D images, etc.
