To create a flowchart or mind map on Whimsical you can start with a template or create from scratch. Either way you can customize every element of your chart by using the editing tools that appear on the left-hand side of the Whimsical editor. You can quickly select shapes and lines to connect in your diagram. Text can be written on any shape that you add to your diagram. And you can even add emojis into the shapes that you use in your diagram.
As is demonstrated in my screenshot above, Whimsical could be a good tool for students to use to create illustrations of government processes like how a bill becomes law in the United States. Another use for Whimsical is to have students outline the progression of a story. Whimsical might also be used by computer science students to create wireframes and user-experience maps.
