In this diagram, we aim to visually represent a building with multiple floors, elevators, and passengers. Each component is depicted using distinct shapes and colors to convey their roles and statuses effectively.

- **Floors**: Each floor is represented by a large, horizontally long rectangle. These rectangles are stacked vertically to reflect the actual layout of floors in a building. Floors are labeled with their respective identifiers (e.g., floor_0, floor_1) to indicate their position in the sequence.

- **Passengers**: Passengers on each floor are depicted as smaller rectangles placed on the left side of the corresponding floor rectangle. The color blue is used for passengers, signifying their status as individuals waiting to board an elevator. Each passenger is labeled with a unique identifier (e.g., p0, p1) for clarity.

- **Elevators**: Elevators are represented by smaller rectangles within the floor rectangles on the right side. We use two distinct colors to differentiate between fast and slow elevators: green for fast elevators and orange for slow elevators. Each elevator is labeled with its identifier (e.g., fast0, slow0-0) and its current passenger count (e.g., 0/2).

- **Legend**: A legend is included to map colors to their meanings: blue for passengers, green for fast elevators, and orange for slow elevators. This ensures that viewers can easily understand the diagram without ambiguity.

- **Text and Status**: Text labels for floors, passengers, and elevators are placed within their respective shapes to ensure clarity. The text color is chosen to contrast with the background color for maximum readability.

The diagram's layout ensures that no two objects overlap, and all labels are clearly visible. This representation provides a comprehensive view of the building's initial state, allowing viewers to understand the positions and statuses of all components at a glance.
