Controls:

"number" controls the number of nodes in the diagram.

Click "<==" or "==> to select the previous or next amount of nodes.

"new setup" creates a new configuration of nodes and lines. The number of nodes stays the same.

"randomize" randomly shuffles the nodes, but keeps the associated lines. E.g., if vertex 1 was connected to vertex 2, this will also be true after the randomizing.

"labels" displays the sequence numbers of the nodes.

"node size" controls the size of the locators.

"show midpoint" triggers the midpoints of all lines to be shown.

"midpoints size" controls the size of the midpoints (displayed as black dots).
