An idea that helps experts see similarities, differences and connections between things.

The idea you're referring to is often encapsulated in the concept of a "concept map" or "mind map." Both are visual tools used by experts to organize and represent knowledge.

1. Visualization of Relationships: Concept maps allow users to visually explore the relationships among multiple concepts. By connecting ideas with lines or arrows, experts can see how different pieces of information are related, highlighting similarities and differences.

2. Enhancing Understanding: This method aids in deepening understanding and retention of information. By breaking down complex ideas into simpler components and illustrating their interconnections, it facilitates easier learning and recall.

3. Promoting Critical Thinking: Creating concept maps encourages individuals to think critically about how different ideas interact and relate to each other, prompting further exploration and inquiry.

4. Applications in Various Fields: Concept maps are used extensively across disciplines—such as education, science, and business—to enhance brainstorming, problem-solving, and planning processes.

In summary, visual tools like concept maps are invaluable for identifying and articulating the similarities, differences, and connections between concepts, thereby improving comprehension and analysis.
