The term schematic refers to a diagram or outline that represents something in a simplified form. It is typically used to describe a visual representation of an object, system, process or concept, which highlights its essential features while leaving out unnecessary details. Schematics are often used in engineering and design to help people understand complex systems more easily, by breaking them down into their component parts and showing the relationships between those parts. In this way, schematic can be thought of as a type of blueprint or map that helps guide someone through a process or system.
