Lecture 02: What is Vis?

by Mike Gleicher on January 28, 2012

Last year this got mixed with overviews, but the lecture notes are useful.

Different readings this year.

Tangles knot of questions:

  • Why do it?
    • What does it work?
    • What is it good for (or not)
    • Why vis instead of X?
  • How do we do it?
    • How to design it?
    • How to realize those designs?
  • When is it good?
  • What are the different flavors of it? (since these may have different answers to the other questions)

Different perspectives on how to come at these questions

Readings

  1. Classifications chapter (from Designing Data Vis)
  2. Kosara: defines vis
  3. Kosara: names of vis
  4. Kosara: many word for vis
  5. Kosara: vis. vs. infographics
  6. smashing magazine dos and don’ts
  7. tufte (and maybe the article about him)
  8. few (the commentary is quite valuable)

a lot of reading (mostly short for 1 day)

Where are these people coming from:

  • Tufte: historian (lesser degree, designer)
  • Smashing Magazine: designers/artists
  • Few: tries to come from all directions (perception, history, practical, design, …)
  • Kosara: academic, tries to be far reaching and connect to others

Some key characters (mentioned in Few)

  • Playfair
  • Bertin – Semiology of Graphics
  • Cleveland and McGill – Graphical Perception
  • Card, Schneiderman, Mackinlay – early infovis manifestos

Note: interaction is missing from lots of these (especially Tufte and Few)

Few:

  • over-simplifies the history
  • too hard on pie-charts (he has his particular mission)
  • has a clear idea of what is good, which makes the other questions easy for him
    • we should always judge a visualization’s merits by the degree to which we can easily, efficiently, accurately, and meaningfully perceive the story that the information has to tell
  • (beware: he’s a pundit and is trying to sell his particular style)
  • basic perception principles (nice since it mixes gestault with lower levels)
  • Rensink (psychologist)
  • Robbins (pundit) – why don’t people buy our books (why are there bad vis)
  • Kosara (academic vis) – interaction and his recent papers
