A mind map is a diagram used to visually organize information. A mind map is hierarchical and shows relationships among pieces of the whole. In education, mind mapping can help students take notes and professors teach course material. One of the most common types of mind map is a large brainstorming web that starts with a central word or idea and then branches out into related subjects.
