Inxigth StarTree Browser
Approach
–First lay out hierarchy on hyperbolic plane and map this
plane to a disk
–Root at center, subordinates around
– Apply recursively, distance
decreases between parent and child as you move farther from center, children go in wedge rather than circle
–Use animation to navigate along this representation of
the plane
Comparison
–Standard 2D browser: 100 nodes (w/3 character text
strings)
–Hyperbolic browser: 1000 nodes, about 50 nearest the
focus can show from 3 to dozens of characters
