= cognitive amplification =
== increased resources ==
: high-bandwidth hierarchical interaction
: parallel perceptual processing
: offload work from cognitive to perceptual system
: expanded working memory
: expanded storage of information
== reduced search ==
: locality of processing
: high data density
: spatially-indexed addressing
== enhanced recognition of patterns ==
: recognition instead of recall
: abstraction and aggregation
: visual schema for organization
: value, relationship, trend
== perceptual inference ==
: visual representations make some problems obvious
: graphical computations
== perceptual monitoring ==

: compact presentation
: multiple attributes simultaneously
: range/distribution/outliers stand out
: recognize patterns, clusters, gaps,
: interaction
::* select, filter, group
::* multiple coordinated windows

= 8 golden rules of info vis =
== large issues ==
choice of services, intended users, ease of learning, range of exploration, etc.
== medium issues ==
use of color, window management, interaction techniques, choice of widgets, data quality, etc.
== small issues ==
terminology, label placement, color, fonts, etc.
# categorical data

:* provide appropriate high quality data for intended users
:* simplify learning, prevent errors, enable shortcuts
:* support exploration with proper widgets
:* coordinate multiple windows
:* strive for consistent terminology, color, fonts, etc.
:* ensure label clarity, complete legends, full titles
