Types of data visualization

Visual Reporting

  1. Visual reporting uses charts and graphics to represent business performance, usually defined by metrics and time-series information.
  2. The best dashboards and scorecards enable the users to drill down one or more levels to view more detailed information about a metric
  3. A dashboard is a visual exception report that signifies the ambiguities in performances using visualization techniques

Visual Analysis
