Computer networks. Be sure to include both the static aspects of the network, such as connectivity, and the dynamic aspects, such as traffic.

Describe how you would create visualizations to display information that
describes the following types of systems.
Be sure to address the following issues:

• Representation. How will you map objects, attributes, and relation-
ships to visual elements?

• Arrangement. Are there any special considerations that need to be
taken into account with respect to how visual elements are displayed?

Specific examples might be the choice of viewpoint, the use of trans-
parency, or the separation of certain groups of objects.

• Selection. How will you handle a large number of attributes and data
objects?
The following solutions are intended for illustration.

The connectivity of the network would best be represented as a graph,

with the nodes being routers, gateways, or other communications de-
vices and the links representing the connections. The bandwidth of the
connection could be represented by the width of the links. Color could
be used to show the percent usage of the links and nodes.
