7. Control-flow diagram - Wikipedia

   en.wikipedia.org/wiki/Control-flow_diagram

   A control-flow diagram ( CFD) is a diagram to describe the control flow of a business process, process or review. Control-flow diagrams were developed in the 1950s, and are widely used in multiple engineering disciplines. They are one of the classic business process modeling methodologies, along with flow charts, drakon-charts, data flow ...

   In computer science, a control-flow graph ( CFG) is a representation, using graph notation, of all paths that might be traversed through a program during its execution. The control-flow graph was discovered by Frances E. Allen, [1] who noted that Reese T. Prosser used boolean connectivity matrices for flow analysis before.
