In this diagram, each object is represented by a specific shape, size, and color to convey its identity, status, and function within the "barman" domain. Rectangles are used for dispensers and shots to denote their container-like nature, while circles represent shakers, indicating their role as mixing vessels. The size of each shape corresponds to the relative size of the object in the domain, with dispensers and shakers being medium-sized and shots being small.

Colors are used to represent the contents and status of each object. For instance, dispensers have colors matching the ingredients they contain (e.g., red for ingredient1 and blue for ingredient2), ensuring easy identification. Shots and shakers are initially colored white to indicate they are clean and empty, which aligns with their status. Text labels within each shape provide identifiers and concise status descriptions, ensuring clarity and readability.

The legend is crucial for understanding the color coding, mapping each color to its corresponding ingredient or status. Relative positions are used to indicate the spatial arrangement of objects: dispensers are placed above shots to imply the flow of ingredients, shots are aligned horizontally, and the shaker is positioned below them, suggesting its role in mixing. Hands, depicted as small rectangles, are shown held by the bartender, indicating their readiness to manipulate objects.

Overall, this visualization strategy ensures that each element is easily distinguishable and conveys its role and status effectively, even to those unfamiliar with the domain.
