  1. Taxonomies Cours de Visualisation d'Information InfoVis Lecture Frédéric Vernier Enseignant-Chercheur LIMSI-CNRS Maître de conf Paris XI

  2. Outline • Introduction to Infovis • Taxonomies • Multi-variate data • Cognitive tasks • Visual Properties • Interaction • Overview+detail • Focus +context • Panning & zooming • Trees

  3. Composition de vues Schema Aspect

  4. Visualization Process Data Data world Point of view on data InteractionLanguage Space Spatial world Point of view on Space

  5. Data Data Point of view on data Space Point of view on space Graphical (road network) Non Graphical (stock exchange) GraphicalAbstraction Point of view on data 1D, 2D, 3D, nD, Time, Trees, Graphs, Non StructuredNon Graphical (stocks by sector) Spatial / Graphical(stocks Values organized by country/state) Nominal, Ordered, Quantitative (N, O, Q)

  6. Point of view on data Data Point of view on data Space Point of view on space Visual cues: lexiconcolor, size, label, shape, ... Layout algo: syntactic Treemaps, City metaphor, Charts, etc. Space 3D 2D Point of view on space(view) Interactive technique: Focus + Contexte Scrolling / Panning Zoom In & Out Fisheye View Deformed Non-Deformed

  7. Graphical Abstraction and Deformation GraphicalAbstraction => 2D space with non label overlapping algo. Alphabetical 1D list => Lines of text with line break rules
