interfaces for big data visualization
Ben Fry, Computational Information Design
visualization extends perception
“Visualization allows people to offloadcognition to the perceptual system, usingcarefully designed images as a form ofexternal memory.
The human visual system is a very high-bandwidth channel to the brain, with asignificant amount of processing occurring inparallel and at the pre-conscious level.”
Tamara Munzner
a visualization turns something you want to find
into something you can see
correlations
clusters
extents
outliers
work with human perception
work with human senseswork with human memorywork with human cognition
you have never seen a violin.
perception involves interactivelydirecting narrow attention
don’t show it all.(you can’t anyway)
filter
summarize
categories = “distance metric” +clustering algorithm
d(x, y) ≥ 0d(x, x) = 0d(x, y) = d(y, x)d(x, z) ≤ d(x, y) + d(y, z)
