A concept map is a diagram or visual representation and organization of knowledge. The diagram is presented in a 2D paper from the top and extends towards the bottom. The core concepts are organized at the top with keywords while its associated ideas lay below in boxes or bubbles and are connected to the central concept via connectors. A concept map follows a hierarchical structure where the relationship between different ideas are articulated through linking phrases, explaining how the ideas are related to each other through short phrases. The method of visualizing the relationships between several concepts is referred to as concept mapping. This graphical tool is a gem for students as well as professionals, including engineers, instructional designers, technical writers, entrepreneurs, and more.
