Hierarchy chart:

Hierarchy chart explains the structure of a program.

When a program with many functions call the other functions, the programmers usually use a tool besides flowchart to represent the complete picture of how those functions are linked with each other.

Hierarchy chart only tells how one function calls the other. It does not give the information about its performance and execution.

It is a graphically representation of the structure of the program. It contains boxes that show each step of the process in the program.
