Presentation Title: Data Visualization

Visualization has become a major means for analyzing big data from a variety of applications. In this presentation, Dr. Han-Wei Shen will give an overview of both the theories and practices of visualization for large scale data sets. In the first part of the talk, Dr. Shen will present the semiology of graphics, which is the theory of visual signs for presenting data. He will discuss how to identify information components from data, the principles of mapping the information components to visual variables, and the compare the effectiveness of different visual variables. In the second half of the talk, Dr. Shen will give an overview of various software tools for creating visualization from data. Finally, he will present several examples created by students in the introduction to data visualization course offered in Spring 2017.
