![This hierarchy chart represents data passing between two modules. When the module Pay_Bill is executed, the pseudocode checks if the bill is already paid by searching for the payment receipt (execute Search_Receipt). If the receipt is not found then it will execute the module Give_Money_To_Debt_Collector to finish the job.](/Images/godic/202502/13/Sample_of_Hierarchy_chart5329.png")

A Structure Chart (SC) in software engineering and organizational theory, is a chart which shows the breakdown of a system to its lowest manageable levels. They are used in structured programming to arrange program modules into a tree. Each module is represented by a box, which contains the module's name. The tree structure visualizes the relationships between modules.
