In the parking domain visualization, the diagram uses geometric shapes, colors, and text to represent the state of curbs and cars. Each curb is represented by a medium-sized rectangle, symbolizing a parking space where cars can be parked. The relative position of these rectangles (curbs) from left to right indicates their sequential numbering in the grid.

Cars are depicted as small circles placed within or behind curbs. A circle inside a curb rectangle represents a parked car, while a circle behind another circle indicates a car that is double parked. The position of the circles (either inside or behind) provides information on whether the car is parked or double parked.

Colors are used to convey the status of cars and curbs:
- Green indicates a "clear" status, meaning the car or curb is free from obstruction, and the car is free to move.
- Red indicates an "occupied" status, meaning the car is parked and not clear to move because another car is double parked behind it.
- Yellow indicates a "double parked clear" status, meaning the car is double parked but is clear to move because there is no car behind it.

Text labels are added to each shape to provide identifiers for curbs and cars, ensuring clarity in the diagram. The text also includes the status of each object, using concise phrases such as "clear" or "double parked."

A legend is included to map each color to its corresponding status, ensuring viewers can easily interpret the diagram. The legend is positioned away from the main diagram to avoid overlapping with any objects, maintaining clarity and readability.

The size of the shapes (rectangles and circles) is consistent to maintain uniformity, and the text is placed with high contrast against the background to enhance readability. The layout ensures no overlapping of objects or text, preserving the integrity of the visualization.
