This example demonstrates how to display a mind map diagram and uses the following features: 1D and 2D Shapes - shows how to create 2D and 1D shapes and how to connect them. Show/Hide Subtree Decorators - shows how to use decorators to show/hide the whole subtree (i.e. all descendants) of a shape. Layouting and relayouting of the diagram - demonstrates how to layout and relayout the diagram when the user toggles a decorator. In that way the diagram always occupies the smallest possible area.
