While the path diagram embedded below illustrates most of the features, its nodes are too crammed.

The path diagram is being rendered within a diagram editor with its own toolbar, which is generally kept hidden in the view mode of this page.

However, you may click "Notices" button next to the search box near top to see the notices. If you are allowed to explore the diagram editor, you'll see a button to make this toolbar visible and use.

You should launch the path diagram editor (click on 'Launch editor'), improve the current path diagram, and save in your workspace. To load any of the path diagram saved in your workspace, launch the editor first, and then click the 'Open path diagram' button, click a file name in the list.
