Choosing data...
• Show only relevant data– Otherwise: clutter
• Show only reliable data– Otherwise: distrust
• Most important data comes first / is more colorful / is larger / etc!
• Provide several views– Layering data vs not layering it

Visualization
”The use of computer-supported,
interactive, visual representations of abstract data to
amplify cognition”

Zooming and
lenses
Semantic ZoomWhen information changes (and typically gets richer) when zooming in.
Magic Lenses: Transparent - Different properties - Change view

Focus + Context
Focus + Context:
To display the most important data at the focal point at full size and detail, and display the area
around the focal point (the context) to help make sense of how the important information
relates to the entire data structure. Regions far from the focal point may be displayed
smaller (as in fisheye views) or selectively omitted.
