In the diagram, each object is represented by a specific geometric shape. The tiles are depicted as rectangles, which are arranged in a grid to represent their layout on the floor. The robots are represented by circles, indicating their ability to move and occupy a tile. Each tile has a status that is visualized using color: a clear tile is colored green, while a tile that is not clear (either occupied by a robot or painted) is colored red. The robots themselves are colored according to the paint color they are holding: white for robot1 and black for robot2. Text labels within each shape provide identification and status information, ensuring clarity and readability. The legend, placed outside the grid, maps colors to statuses, helping users quickly interpret the diagram. The contrast between text and background is maximized for readability, with text in dark colors on light backgrounds and vice versa.
