is a faint or translucent “barely there” rendering. In Gephi, you can do this
by using operation filters to identify the set of nodes that exists before the
current time span, but are
not
in the current time span, and resetting their
colors to something close to the background color. This is a bit of a tricky
one-off process in Gephi, but the results indicate the value of this graphical
technique.
The four frames of
Figure 15-4
show the current graph in full color at
successive times, with the nodes and links that are no longer part of the
graph shown in light gray. Ghosting a previous state provides the perfect
frame of reference for understanding change. The added advantage of this
approach in a live context is that you can interact with the still-present
ghosted nodes to make sense of the changes.
