Visualization, whether scientific or information, is now being used by almost every organization today. Scientific visualization is a key component of medical, engineering and physical data analysis and Information Visualization breathes life into business, financial and textual data. Whether in the research and development of electronic imaging devices or simply getting directions from one address to another, we have become dependent on visualization. In this course, we will briefly cover the history of visualization and its relationship to computer graphics, imaging, and visual analytics, review the most common and successful visualizations, discuss advanced visualizations, many integrated with analysis (the new visual analytics) and explore on-going research, especially in the area of high dimensional data visualizations. We will also provide an overview of various visualizations systems currently available.
