"A picture is worth a thousand words." The human race is wired to perceive pictorial messages and discover patterns using intuitions.  In a data-€driven business environment, the ability to convey hard messages with clever visualization is essential and valuable. In this course, we will explore ways to organize and derive meaning from vast amounts of data by using visual presentation tools and techniques. Students will learn concepts, methods, and applications of data visualization methods.  The course will introduce interesting examples in different application areas. Students will also learn visualization tools from GUI-based software, to more advanced programmable visualization packages in R language.  They will be guided in creating engaging and interactive visualizations.
