Data has a story which has to be told! Data visualization is all around us, in print and in electronic media. Some of it is accurate and effective, while some is extremely unclear, confusing, or misleading. In this course we will study various approaches to information visualization and associated data analysis techniques. How do we take a lot of data, or very complex data, and present it in ways that allow it to communicate information clearly and effectively? The course will explore applications from science, medicine, social science, and humanities.
