VIAssist emplos distinct visualization tools for the purpose of analyzing massive datasets.  VIAssist systems configured with a dual monitor interface provide a summary visualization, or view, of the VIAssist data repository from one monitor while simultaneously displaying details from a second monitor.  Similarly, summary and detail visualizations can be docked directly in the VIAssist workspace for systems using a single monitor interface.  Although summary information is ideal for a cursory look at a data source, you may choose to display only detailed views or summary views.  Regardless of the combination of visualizations you choose to create, multiple and coordinated views of a data source using VIAssist provide visualizations of patterns, trends, anomalies, and associations within the data source which would otherwise be difficult or time consuming to expose. 

Over a dozen visualization utilities are available in VIAssist offering an analyst the flexibility to choose the visualization that is appropriate for the task at hand.  The user may interact with data elements within a view by highlighting or, in some cases, manipulating the visualization directly.

The following subsections present examples of the processes that may be used in exploring and analyzing a data source.  The examples below generally increase the signal to noise ratio of VIAssist visualizations by doing one or more of the following: 
 

• utilizing summary and detail coordinated views
• focusing on a subset of data
• visualizing few data elements with low cardinality
• relying on visualization cluster counts
