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 (Mac: SHIFT and CMD).
• To switch the display from an inner graph to its parent graph click on the background while pressing SHIFT and CTRL (Mac: SHIFT and CMD).

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