This document discusses different tree structure diagrams that can be used to represent hierarchical relationships including classical node-link diagrams, nested sets, layered "icicle" diagrams, outlines and tree views, and nested parenthesis. It was authored by Mr. For-Ian V. Sandoval for an ITEP 214 class on representing hierarchical data in multiple formats.
