nodeLabels

mandatory

Array of strings

[ "*" ]

An array of node labels visible in the project. Nodes that are not listed are not visible in the project. The "*" value means all existing labels are visible. An empty array is not a valid value for this setting.

relationshipTypes

mandatory

Array of strings

[ "*" ]

An array of relationship types visible in the project. Relationship types that are not listed are not visible in the project. The "*" value means all existing relationships are visible. An empty array is not a valid value for this setting.

calculateNumOfRelatedNodes

Boolean

false

If set to false, the "_numOfRelatedNodes" system property is not calculated in visualization. This leads to more performant queries in bigger graphs, especially with high-degree nodes. By default it’s set to false and should be changed to true only when needed (which is quite rare).

calculateNumOfRelations

Boolean

true

If set to false on a Gremlin-based graph database (e.g. Azure Cosmos DB, or JanusGraph), the "_numOfRelations" system property is not calculated in visualization. This leads to more performant queries in bigger graphs, especially with high-degree nodes. With this feature disabled, you won't be able to see if a node is expandable (but it still will be expanded when using the expand function).

nodeUid

Object

If present, this object defines the configuration for UID usage in saved visualizations. For more information see UID in Saved Visualizations.

nodeUid.labels

Array of strings

An array of strings representing node labels that are used for UID functionality. All nodes have to be covered with these labels.

If the array is empty, all labels in the database are used (updated on config save or when opening any saved visualization).

nodeUid.property

String

Property key name where the UIDs are stored on nodes.

nodeUid.manageIndex

Boolean

false

Neo4j connections only!

If set to true, the node UNIQUE SCHEMA indexes are automatically created in Neo4j for every combination of nodeUid.labels and nodeUid.property to ensure optimal performance on visualization loading. This ensures that the visualization loading will be as fast as possible.

relationshipUid

Object

If present, this object defines the configuration for UID usage in saved visualizations. For more information see UID in Saved Visualizations.

relationshipUid.types

Array

Empty array

An array of strings representing relationship types that are used for UID functionality.

If the array is empty, all labels in the database are used (updated on config save or when opening any saved visualization).

relationshipUid.property

String

Property key name where the UIDs are stored on relationships.

relationshipUid.manageIndex

Boolean

false

Neo4j connections only!

Neo4j 4.x

For UID to work with relationships, a fulltext index is needed (because Neo4j before version 4.3 doesn't have implicit indexes for relationships).

Neo4j 5.x

If set to true, the node UNIQUE SCHEMA indexes are automatically created in Neo4j for every combination of relationshipUid.types and relationshipUid.property to ensure optimal performance on visualization loading. This ensures that the visualization loading will be as fast as possible.
