Sometimes it's easier to show something graphically than it is to describe it with words. That's the beauty of flowcharts. Flowcharts explain a process clearly through symbols and text, giving your audience the gist of the process in a single glance. We can use Visio, Mac-based alternatives, PowerPoint, Illustrator, or other tools to create simple and elegant flowcharts, although with clickable pop-up callouts when further explanation is required.
