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
