25.11 Displaying Implied Edges for Hidden Vertices
You can view implied edge connections for hidden vertices in a graph visualization using Graph Explorer.
When you hide vertices in a graph visualization, the hidden vertices and their corresponding edges are removed from the view. This can make the remaining graph elements appear disconnected, even when the visible vertices are still connected through hidden nodes.
For example, in the following figure, the left visualization shows
EMPLOYEES connected to DEPARTMENTS, which in turn
are connected to LOCATIONS. The image on the right shows the resulting
visualization when the DEPARTMENTS vertices are hidden.

To preserve edge context, you can use the 
option (shown highlighted in red in the following figure) in the
Edges legend region to collapse hidden paths. When enabled,
implied connection are drawn between visible vertices that remain connected through one
or more hidden vertices. These implied connection are typically shown as dashed edges to
distinguish them from actual edges in the graph, as shown in the following figure:
