Labels Issue

[krs-world]

It looks like for the tree and linked list (havent checked) we see the right menu on the bridges visualization two items - Node Labels and Node Links, which work. But when I put up a graph, these labels are not available. While this might be an oversight, hitting the 'l' button doesnt toggle the labels anymore. Good idea to have the menu buttons for graph and perhaps other data structures if it they have labels.

Matthew did you work on this? Assigning to you.
