An organizational chart. 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.
A company's organizational chart typically illustrates relations between people within an organization. Such relations might include managers to sub-workers, directors to managing directors, chief executive officer to various departments, and so forth. When an organization chart grows too large it can be split into smaller charts for separate departments within the organization.
