Visual Analytics Definition
Visual analytics is the science of analytical reasoning facilitated by interactive visual interfaces.
People use visual analytics tools and techniques to Synthesize information and derive insight from massive, dynamic,
ambiguous, and often conflicting data Detect the expected and discover the unexpected Provide timely, defensible, and understandable assessments Communicate assessment effectively for action.
“The beginning of knowledge is the discovery of something we do not understand.” ~Frank Herbert (1920 - 1986)
