class diagram

A class diagram is a visual representation used in software design to outline the structure of a system. It illustrates the different "classes" or components that make up the system, showing their attributes (like properties) and methods (like functions). The diagram also highlights how these classes relate to one another, such as inheritance (one class deriving from another) and associations (how classes interact). Essentially, class diagrams help developers plan and communicate the organization of code, making it easier to design and understand complex systems in a systematic way.
