'''Flow diagram''' is  a [[diagram]] representing a flow or set of dynamic relationships in a system. The term flow diagram is also used as a synonym for [[flowchart]],<ref>Robert L. Harris. ''[https://books.google.com/books?id=qusmDAAAQBAJ&q=%22flow+diagram%22 Information Graphics: A Comprehensive Illustrated Reference].'' 2000. p. 153-155</ref> and sometimes as a counterpart of the flowchart.<ref name="Ha 1999 156">Harris. (1999, p. 156)</ref>     

Flow diagrams are used to structure and order a [[complex system]], or to reveal the underlying structure of the elements and their interaction.<ref>Urs B. Meyer et al. ''Process Oriented Analysis: Design and Optimization of Industrial Production Systems.'' 2006. p. 38.</ref>
