Mind mapping is the process of using visual diagrams to show the relationships between ideas or information. Its popular uses include project planning, collecting and organizing thoughts, brainstorming and presentations — all in order to help solve problems, map out resources and uncover new ideas.

It can be more useful than trying to keep track of our ideas by scribbling them on paper, and can aid in manipulating and generating concepts.
