Data Analysis Tools in Sentinel Visualizer's Link Analysis Diagram

Data Analysis on the Visualizer Diagram

After using search to add entities and relationships on a Visualizer diagram, data analytics are available to find, filter, add, color and analyze.

Find an entity on the diagram by searching for its name (Ctrl +F)
Easily reduce the diagram to just the selected entities with or without their connected entities
Only display linked or unlinked entities
Filter the data by removing entities and relationships based on their characteristics
- Filter entities based on their details like Entity Type
- Filter entities based on numeric range values (low and high values)
- Filter relationships on their details like Relationship Type
- Filter relationships based on numeric range values
- Use the same data refinement to limit new data retrieved via Get Links

Color and size entities on a gradient scaled based on their metrics
Color and set the thickness of relationship lines on a gradient scaled based on their metrics
Select two entities and perform Shortest Path and All Path analysis between them
Identify entity cut-points to disrupt a network
Calculate Cliques of closely connected entities within a network
Select and filter individual networks
Apply date information for Temporal filtering and analysis
Calculate metrics like Social Network Analysis (SNA)

Entity Selections

The Entities panel offers options to customize the display of entities on your diagram. When you click on an entity, it turns green and the entities connected to it are highlighted in blue. Easily reduce the diagram to just the selected ones with or without their connected entities.

Entities panel offers many display options

The Show/Hide options let you just see the Linked Entities or Unlinked Entities. You can also show or not show the name labels of each entity, and the icon to expand or collapse their connections.

Relationship Line Options

The Relationships panel offers options to customize the display of the lines on your diagram. Optionally display labels, sums, arrows, and whether the lines should be straight or angled.

Relationship Line Sum Customization Relationship Line Sum Numeric Customization of prefix, units, decimals and suffix

Entity Range Filters

The Range Filter limits the entities in the diagram based on the low and high values of an entity metric. It can be set using a Squelch min/max bar or with explicit numeric values. The refresh button fills the minimum and maximum values for the data in the diagram which can be useful even if you don't filter the data. The range can be restricted to specific entity types.

Example of a filter for Entities with 4 to 35 Relationships.
Some entities become disconnected because they are connected to entities that don't meet the filter criteria.

Squelch on many types of numeric values at the entity level, its network size, its entity type, SNA values, and combinations of them

Relationship Range Filters

The Range Filter limits the relationships in the diagram based on the low and high values of a relationship metric. It can be set using a Squelch min/max bar or with explicit numeric values. The refresh button fills the minimum and maximum values for the data in the diagram which can be useful even if you don't filter the data.

Example of a filter for Relationships with a Line Sum of 300 or more.
Lines with lower values are hidden. Switch to Entities panel and select Linked Entities to focus on the most important.

Squelch on many types of numeric values and optionally restrict it to specific relationship types

Entity Data Refinement

Data Refinement lets you further define the entities you want to keep on your diagram. The options are identical to the Entity Search's Advanced option and Entity Filter in the Advanced Dataset Builder. These settings are also used to limit the entities retrieved when Get Links adds additional entities.

Relationship Data Refinement

Data Refinement lets you further define the entities you want to keep on your diagram. The options are identical to the Relationship Search's Advanced option and Relationship Filter in the Advanced Dataset Builder. These settings are also used to limit the entities retrieved when Get Links adds additional entities limited to these relationships.

Visualize Gradient Metrics to Highlight Important Parts of Your Network

Visualize your data even in the most complex inter-related network diagram.

A wide range of metrics are generated to quickly see central and highly-connected players in your network diagram. Sentinel Visualizer applies numeric rankings to the visual appearance of the network. You can specify the colors for low and high values and relative size for entities and relationship lines.

Gradients Options for Visualizer Example of Entity gradients and size based on Lines In, and Relationship Lines based on Relationship Count per Line

Gradient Metadata Coloring

Entity metadata values can use lookup values defined with colors to quickly identify them on the Visualizer Diagram.

Example of contact tracing with infected individuals in red

Finding the Shortest Path and All Paths Between Entities

If you identified two entities of interest, you probably want to know how they are connected. Quickly see one of the shortest paths, or all paths based on a maximum number of degrees between them. You can filter out all the other entities on your diagram.

You can also start by selecting multiple entities and use the Get Links, Between Selected feature to add the fewest entities to connect them to each other.

Cut-points

Sentinel Visualizer identifies and displays network cut-points. The removal of these entities seriously disrupt or completely destroy the link between sub-groups.

Select cut-points to highlight the entities, then click the filter checkbox to just show them

Network Selection

Each disconnected set of entities is a network. Each network is listed with its entity count. Select one to see it highlighted on the diagram.

Select Networks to list them, select one to highlight it, then click the filter checkbox to just show the network's entities

Cliques

By analyzing the results of network statistics, Sentinel Visualizer pinpoints and provides a visual representation of cells or cliques: groups of entities within a network that are closely connected to each other.

Select Cliques to list the cliques in your diagram. Select one to highlight it. Click the filter checkbox to just show its entities

Temporal Analysis

Sentinel Visualizer provides a powerful Time Range interface that hides or shows data based on a time slider control. Temporal Analysis makes it easy to see how networks form, change, and interact with each other over time. This capability allows you to spot patterns and predict actions and behaviors. The Time Range interface supports ranges down to the second level, and includes the ability to visually define time spans and ranges.
