The document discusses the structure and design of JavaFX applications. It explains that JavaFX uses a scene graph to organize visual elements in a tree structure with nodes like stages, scenes, containers and controls. It also covers using FXML to define the view and a controller class to link the view to the model/logic. Stylesheets are used to separate design from code. Common elements like media players, effects and animations are demonstrated.
