Providing drawings here is not possible within this text format. However, I can describe how DOL (Direct Online) and Star-Delta starter are typically represented in schematic diagrams. A DOL starter connects the motor directly to the line voltage without any transformer or starting resistor. In a schematic, it's usually represented by placing the motor symbol (which consists of an outline of the motor body, rotor, and stator) directly on the power supply lines. A Star-Delta starter connects the motor windings in star configuration during starting to reduce the starting current, and then switches them to delta configuration for efficient running. In a schematic, it's usually represented by connecting the motor symbol with three lines (star configuration) to the power supply initially, and having three contacts (one per line) that are switched to connect the motor in delta configuration after starting.
