Approaches


Why
Visualize
Data?

•  Spreadsheets
are
great…
but
it’s
diﬃcult
to

understand
with
large
datasets

•  Examine
Concepts
from
mul0ple
perspec0ve

–  Spa0al

–  Temporal

•  Integrate
data
from
mul0ple
sources

•  Ex.
Fault
lines,
earthquakes,
and
popula0on
data

•  Interac0ve
≠
expensive
or
diﬃcult
