Homework #1 Due today

Star Coordinates Continue discussion… Kandogan, “Star Coordinates” Rohit, David

Table Lens Rao, “Table Lens” Harsha, Vishal

VisDB Keim, “VisDB” Ming, Rui

Comparison of tools Parcood: <1000 items, <20 attrs Relate between adjacent attr pairs Starcoord: <1,000,000 items, <20 attrs Interaction intensive Tablelens: similar to par-coords more items with aggregation Relate 1:m attrs (sorting), short learn time Visdb: 100,000 items with 10 attrs Items*attrs = screenspace, loooong learn time, must query! Spotfire: <1,000,000 items, <10+infinity attrs Filtering, short learn time
