Module Hierarchy Chart

The hierarchy chart is a graphical representation that is used to represent the relationship between various modules or systems in an organization. In programming, a hierarchy chart is used for representing an organizational framework. The hierarchy charts can also be utilized to show an organization’s reporting structure. In such a hierarchy chart, the President is at the top, the Vice Presidents are on the next level which is lower than its predecessor, and so forth.
