This is a demonstration of the path tracing functionality. Nodes here are positioned randomly
and then moved as if they were connected with springs to each other.
- Click a node to select it. Then click another node. The shortest path between the two nodes
will be traversed with an overlay. If no path exists, an alert will show.
- Click the 'Pencil' icon to enter 'select' mode, then select several nodes. Click the canvas to exit.
- Click the 'Home' icon to zoom out and see all the nodes.
- Use the pause/play/cancel buttons to change the state of the path trace animation.
