Annotations are used to add visual content and help set context for both models and interfaces. The annotation button and videos are only available on the interface, but text and graphics can be used in both models and interfaces. The model view, which is available only on the interface, allows you to expose model structure to the interface user. It resembles a graphics box in that it displays a picture to the user, but it's much more powerful, allowing you to choose which elements of the model to include and displaying results by including graphs and tables from the model. Model views are also used in storytelling and can be used to control which variables are included in a simulation.
