A use case diagram is a visual representation that highlights the functionality of any system or application from the user's perspective. It illustrates the interaction between the system, users, and the use cases that the system supports. 


For example, you own a restaurant and you wish to document the various tasks or services that the restaurant provides to its customers. A use case diagram will help you visualize and organize these tasks. 


Now, in your restaurant’s use case diagram, the actors will be the ‘customers’, ‘chefs’, and ‘waiters’. The use cases, that are the services or tasks, will be ‘place order’, ‘pay bill’, ‘view menu’, etc. With the help of a diagram, you can draw lines to mark associations of the actors with the use case. Like the customer (actor) will be associated with the view menu (use case). Here it establishes that the customer needs to view the menu in order to place the order.


By mapping this information in a use case diagram, you can effectively visualize and communicate the different tasks your restaurant provides to its customers and the role of each employee.
