  1. 34 x 72 68 23180 24248 Information Visualization External Cognition Using perception to amplify cognition

  2. Information Visualization Information Design/Data Graphics Using external representations to amplify cognition Using abstract external representations

  3. Information Visualization Using interactive external representations to amplify cognition • Scientific Visualization = physical data • Information Visualization = abstract dataWWW server logs, databases… => No intrinsic visual representation

  4. History 10 years of Academic Research Jacques Bertin (cartograph) invented the domain in the 60’s Ben Shneiderman popularized it (~90’s ) Topology ofInternet by service provider

  5. Example : Table Lens Take a spreadsheet, replace figures with bars + add interactive manipulation of rows and columns http://www.inxight.com

  6. Starfield Display (plots) 2D plots with interactive filtering and navigation

  7. Treemaps For hierarchical and clustered data Micro/macro reading, size + color encode information http://www.smartmoney.com/marketmap

  8. Treemaps (2) 800000 hits in 6 months, interactive display
