Prefuse Components

Information Input

• GraphML file
• TreeML file
• MySQL database connection
• CSV File
• Runtime Data Creation

Visualization Object

• Interface between onscreen visualization and data
• Maintains Action Lists
• Creates interface for grouping data objects based on search queries

VisualItems

• Responsible for storing the visual information for individual tuple sets (data columns)
• Generally Manipulated through ActionLists

ActionLists

• Allows for the organization of as many different combinations of display filters, force simulators, and animation effects
• Linked to a specific visualization object, can be called once, set to run constantly, or in response to user input

Tuple Sets

• Groupings of information based on a user defined groupings
• Can be assigned manually or created on the fly
• single node can belong to multiple Tuple Sets

Predicates

• Basic objects for searching
• based on prefuses internal data search language
• really poorly documented

Rendering

• Render Objects
  • Color Actions
  • Label Renderer
  • Shape Renderer

• Render Factory
  • Determines which data objects are rendered in what manner
  • Can be triggered through action lists as well as dynamic search Predicates
  •  

Data Structures

• Tree
  • Hierarchichal Tree Format
• Graph/Table
