From Wikipedia
An organizational chart, also called organigram, organogram, or organizational breakdown structure (OBS), is a diagram that shows the structure of an organization and the relationships and relative ranks of its parts and positions/jobs. The term is also used for similar diagrams, for example ones showing the different elements of a field of knowledge or a group of languages.
