What is the definition of a diagram in English not math?

In English, a diagram is a visual representation of information or data. It's a simplified drawing that uses symbols, lines, and shapes to illustrate a concept, process, or relationship. Think of it as a visual explanation that makes complex things easier to understand.

Here are some examples:

* A flow chart: Shows the steps involved in a process, like how to bake a cake.

* A family tree: Depicts the relationships between family members.

* A map: Illustrates the layout of a city or country.

* An organizational chart: Shows the structure of a company or organization.

* A blueprint: Shows the layout of a building or product.

Essentially, a diagram is a visual tool that helps us understand information more quickly and easily. It's a way of "seeing" what words alone can't always convey.
