What Are Mind Maps?

Before diving into their application in coding, let’s first understand what mind maps are. A mind map is a diagram used to visually organize information. It typically starts with a central concept or idea, from which related ideas, words, and concepts branch out. This radial structure allows for a natural flow of thoughts and helps in creating connections between different elements.

Mind maps were popularized by British author Tony Buzan in the 1970s as a note-taking and brainstorming technique. Since then, they have been adopted across various fields, including education, business, and personal development. In the context of coding and programming, mind maps serve as an excellent tool for breaking down complex concepts, visualizing algorithms, and planning project structures.
