Visualization Analysis and Design

Presentation Munzner, T. (2015). Visualization Analysis and Design. CRC Press. Visualization: Computer based visualization systems provide visual representations of datasets designed to help people carry out tasks more effectively. Visualization is suitable when there is a need to augment human capabilities rather than replace people with computational decision-making methods. A visual representation is an external representation that replaces cognition with perception in an attempt to confirm expected and find unexpected patterns as well as assess validity of statistical models.
