What is graph?-Myra

• A graph is a person designed to express words

• Graph is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe

• In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The points on the graph often represent the relationship between two or more things.
