==============

I draw Data-Control flow diagrams for better understanding of some process in code. It looks something like that:



Legend:

• ---> – control flow
• ==> data flow
• Ellipsis – method
• Rectangle – data storage
• Rectangle with rounded corners – class
• If ellipsis is located on the border of a class – it is a public method

Such diagrams help me later to understand place of some piece of code in some process in system.

It is critical not to draw unnecessary details on a diagram and stay focused on the current task, in other case a diagram will be unreadable. For example diagram in this post is near the edge of readability – lots of intersections are signs of it.
