How can we define "good" visualizations?
In this class, we discuss several aspects of good visualizations, in
particular the graphical integrity as E. Tufte puts it. There are many
ways to lie with visualizations. Some are
blatant
lies; some mixes up
correlation
and causation; some accidentaly or intentionally omit important
contexts. Why is it important to discuss about these cases in
visualization?
History of visualizations
If we look at the history of arts, there is a tendency of moving from
concrete to abstract. There is also an interesting contrast between
sculptures (3D) and paintings (2D). There is a huge gap, more than
thousand years, between realistic sculptures and realistic paintings
with correct perspectives. These observations provide an interesting
insight on the history of visualization. The 'abstraction' — data
maps, time series, etc. — occurs after a long history of cartography.
