HUMAN COMPUTER INTERACTIONS(HCI)

Q5. With the growing prominence of “networked” data in the physical, social, and
economic sciences, there has been a proliferation in graph visualization applications.
However, as the size and complexity of the underlying graph data grows, many
representation and interaction challenges arise. Please consider and describe a
multivariate, temporal network visualization context of interest/knowledge to you and
then answer the following questions:

A. What representation and interaction issues do you need to consider if you want to
facilitate top-down (overview first), bottom-up (start with what you know), and middle-out
(relevant subgraph) exploration?

B. How do the considerations identified in (a) change when you think about i) different
display sizes (small versus large) and ii) different input mechanisms (mouse versus
touch)?
