what is data visualization?
imposing space/time on data
for example
cartesian coordinate system
hans rosling's bubble chart
fertility rate
life expectancy
fertility rate y axis
life expectancy x axis
population radius
region color

problems for data exploration
hit a limit at 5-6 dimensions
more dimensions more problems
how can we work with dozens of dimensions?
and another thing!
dimension encodings are qualitatively different
position, color, radius
how can we give equal weight to every dimension?
