Visualization Interactions

• Domain data interactions
  • browsing - get "the big picture"
  • sampling - reduce data size
  • directed, "ad-hoc" querying
  • associative data access
• Visualization domain interactions
  • load / store of mappings and settings
  • graphical interactions that could become domain data interactions
• Used to input queries to
  • the visualization process
    - to create, edit, manipulate visualization networks
  • the data
    - to specify (typically once) data files to be retrieved
    - to specify data fields to be displayed
    - specify visualization pipeline parameters
  • the visualization output
    - to create/manipulate the output (for further queries)
    - to display further available information about the data
• Often use Graphical User Interfaces (GUIs)
