This document contains the notes from a lecture on information visualization given by Erik Duval. It discusses state-of-the-art evaluation methods for information visualization, including controlled experiments, usability evaluations, case studies and natural environment studies. It also mentions challenges with evaluation and replicating results. The notes raise questions about the students' work and plans for a final demo the following week.

9. Vague…
“The data speaks for itself and
redundant non-data-ink was removed
to keep the visualization clean and
simple.“
“narrowing it down helps to avoid
certain problems and trade-offs”
