  • Information Visualization Course Informatica Umanistica Università di Pisa Lecture I – 24 th February 2010 Emanuele Ruffaldi PERCRO - Scuola Superiore S.Anna
    • Term Visualize
    form a mental image of something to make perceptible to the mind
  • Visualization in the Past http://www.math.yorku.ca/SCS/Gallery/milestone/ Oldest Known Map (Museum at Konya, Turkey) c. 6200 BC Oldest World Map by Anaximander of Miletus c. 550BC
  • Visualization Today Evolution of Storage MIT, Real Time Rome Rosling @ TED New York Tube (NYT) RoamBi Enabling Technology Laboratory in the UAB School of Engineering
  • Information Visualization
    • The purpose of
    • visualization is to
    • convey information to
    • people through
    • graphical means
    Pat Hanrahan, Barbara Tverski, et al.
  • Visualization Goals
    • Macro Goals
      • Record
      • Analyze
      • Present
    • Effects
      • Map
      • Abstract
      • Clarify

      • Communicate
      • Discover
  • Clarify http://homepage.ntlworld.com/clivebillson/tube/tube.html
  • Clarify First Clear map of London Tube by Harry Beck in 1931 (Topology Based)
  • Interaction G-Peak by Oblong
  • Information Explosion
    • The Industrial Revolution of Data ( Joseph Hellerstein , UC Berkeley)
  • Challenges
    • Information Explosion
      • Increasing amount of data
      • How to Select?
    • Visual Form
      • Many different ways of representing data
      • Which Visualization?
    • Interactivity
      • Interactivity improves visualization
      • Which Interaction metaphor?
  • Visualization Process Data Acquisition Scraping Visualization Design Evaluation Interaction Data Processing Decision Problem Statement
  • Information Model
    • Entities
      • Single elements with Attributes
    • Relationships
      • Associations between Entities
      • With their Attributes
  • Representation
    • Semantic
    • Arbitrary
    • Conventional
  • Data Types
    • Attribute Quality
      • Nominal (Categorical): Fruits, Colors,…
      • Ordinal (Ordered): Days, Ratings
      • Quantitative
      • Interval : time
      • Ratio
    • Attribute Dimensionality
      • Dimension like 1..2… for vector
