This application demonstrates navigating in a grouped graph and incremental layout.

• To open a closed group node click on its plus icon.
• To close an open group node click on its minus icon.
• To switch the display to the inner graph of a group node click on it while pressing SHIFT and CTRL.
• To switch the display from an inner graph to its parent graph click on the background while pressing SHIFT and CTRL.

Opening and closing group nodes additionally triggers an incremental layout, such that the overall layout style is maintained.
