Flowchart

A flowchart is a diagram representing the flow of logic, algorithms, or data through the use of boxes, lines, and arrows. Programmers sometimes use them to plan out the logic of their programs prior to implementing them in code via a programming language, or to document the logic after the program is written.

The ISO 5807:1985 and ISO 10628 standards relate to flowcharting.
