1. AGENDA: 06/09/2014 Discuss information visualization methods. Tables, diagrams, charts, bullet points Words vs. pictures vs. numbers Visualization that must stand on its own vs. those accompanied by talk. Evaluate information visualization methods. Look for level of content. Does it transmit rich content? What are the strengths/weaknesses? Are there other ways that the material could be presented?

3. INFORMATION VISUALIZATION Definitions of information visualization related to technology: The study of how to effectively present information. The use of computer-supported visual representations of abstract data to amplify cognition (from Readings in Information Visualization).

4. INFORMATION VISUALIZATION IS DESIGN, NOT ART Art and design are not the same. Art is valued for its originality and expressiveness. Art is valued for pushing the bounds of accepted norms and potentially expanding the definition of those norms. Design is valued for its fitness to a particular user or task. Design is valued for its effectiveness and use. Design requires that the designer know the audience, use, task, and objectives to be accomplished. 4
