    Microsoft Visio is frequently used for this type of diagramming. Visio is a
    traditional part of Microsoft Office, but it is sold separately, which has limited
    its use. But it is still a ‘go to’ product. If you have access to a copy of Visio,
    you can use Visio.
    Lucidchart is a competing product that offers a free version of its product and
    can be used as well for this exercise.
    Note: The flowchart symbols were popularized by IBM in the 1960s. See the
    image below of an IBM Flowchart stencil.
