"Flowcharts visualize the flow of a process or event step by step leading to its outcome. It’s a great tool to graphically capture the thinking process in a logical and organized manner during note-taking."
In business use, drawing a flowchart involves the use of many symbols, however, for education purposes, the basic shapes of Start and End (oval), Process (rectangle), and Decision (diamond) will suffice. Arrows are used to connect the steps and indicate the flow of action."
