Visual analytics is the science of analytical reasoning facilitated by interactive visual interfaces. [Thomas and Cook, 2005]
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; and communicate assessment effectively for action.


Visual analytics is a multidisciplinary field that includes the following focus areas:

  • analytical reasoning techniques that let users obtain deep insights that directly support assessment, planning, and decision making;
  • visual representations and interaction techniques that exploit the human eye’s broad bandwidth pathway into the mind to let users see, explore, and understand large amounts of information simultaneously;
  • data representations and transformations that convert all types of conflicting and dynamic data in ways that support visualization and analysis; and
  • techniques to support production, presentation, and dissemination of analytical results to communicate information in the appropriate context to a variety of audiences.

Visual analytics as a highly interdisciplinary field of research.
[Keim et al., 2006]
Visual analytics is more than just visualization and can rather be seen as an integrated approach combining visualization, human factors and data analysis. ... With respect to the field of visualization, visual analytics integrates methodology from information analytics, geospatial analytics, and scientific analytics. Especially human factors (e.g., interaction, cognition, perception, collaboration, presentation, and dissemination) play a key role in the communication between human and computer, as well as in the decisionmaking process.
[Keim et al., 2006]

Visual analytics is the formation of abstract visual metaphors in combination with a human information discourse (usually some form of interaction) that enables detection of the expected and discovery of the unexpected within massive, dynamically changing information spaces. It is an outgrowth of the fields of scientific and information visualization but includes technologies from many other fields, including knowledge management, statistical analysis, cognitive science, decision science, and others.

This marriage of computation, visual representation, and interactive thinking supports intensive analysis. The goal is not only to permit users to detect expected events, such as might be predicted by models, but also to help users discover the unexpected—the surprising anomalies, changes, patterns, and relationships that are then examined and assessed to develop new insight.
