supports interactive three-dimensional exploration of experiment
network topologies, and scales to very large topologies.
Here is
a before-and-after view of a moderate-sized network with 541
nodes.
First is the static 2D Graphviz view, using an algorithm
which is perfectly adequate for smaller topologies.
Then a
snapshot
from hypview of the same topology, where more detail is apparent.
Interactively, it is easy to reach out from the high-detail area in the
center of the sphere to look more closely into the compressed areas
near the center of the sphere.
