You can add entities with a spatial location to a map. This allows you to see spatial relationships between entities that are not apparent in a nongeographic view.
When you add entities and relationships to a map, a knowledge graph layer is created in the Map Contents pane (1). A knowledge graph layer is a composite layer with a knowledge graph as its data source. The knowledge graph layer contains knowledge graph feature sublayers and knowledge graph table sublayers. Knowledge graph feature sublayers provide access to entity and relationship types where their instances can have spatial features. Knowledge graph table sublayers provide access to nonspatial entity and relationship types.
You can create a blank map from the Investigation Contents pane or you can start from any of the views in which you work with a knowledge graph: link charts, the knowledge graph view, data cards, global search and other maps. You can select entities and relationships in the active view and add them to a new map. After adding content from a knowledge graph to a map, use the Context Toolbar (2) to work with graph layers in much the same way you work with feature layers and stand-alone tables.
Open a feature sublayer's attribute table to see the properties of entities that can have spatial features. Open a table sublayer in the knowledge graph layer to see the properties of nonspatial entities and relationships.
Note:
You can only open thirteen content items at the same time in Knowledge Studio. If you have reached this limit, you will need to close a tab before you can open a map.
Create blank map
You can create a blank map directly from the Investigation Contents pane. Use any of the other methods listed to add data to your map.
- In the Investigation Contents click Add Content.

Add a knowledge graph layer from the knowledge graph view
You can add a single record, an entire entity type, or specific instances of an entity or relationship type to a map from the knowledge graph view. When you add content to a map, a knowledge graph layer representing the entire knowledge graph is created and added to the map. New maps appear in the Investigation Contents pane.

- Click the appropriate option to add a knowledge graph layer to the map.
- Under Add to new..., click Map to create a map in the project.
- Under Add to existing..., click the name of an existing map.
- Under Add to new..., click Map
Note:
If you add an entire entity or relationship type to a map from the knowledge graph view, you cannot remove individual entities or relationships of that type.
Add an entire knowledge graph
All instance of an entity or relationship type can be added to a map.
- In the contents pane, click Add Selection To next to the knowledge graph you want to add to the map.
- Click the appropriate option to add a knowledge graph layer to the map.
- Under Add to new..., click Map to create a map in the project.
- Under Add to existing..., click the name of an existing map.
- Under Add to new..., click Map
Note:
You cannot remove entities and relationships when you add an entire knowledge graph to a map from the knowledge graph view.
Add a knowledge graph layer from global search
Entities and relationships returned in global search results can be added to new or existing maps.
- Select a record by clicking its checkbox.
- Click Add Selection To at the top of the Search results pane.
- Click the appropriate option to add the selected records to the map.
- Under Add to new..., click Map to create a map in the project.
- Under Add to existing..., click the name of an existing map.
- Under Add to new..., click Map
Add a knowledge graph layer from a link chart
After you create a link chart from an investigation's knowledge graph, you can add records from the link chart to a map.
- Select the entities and relationships in the link chart that you want to add to the map.
- Hold the Ctrl key and click the entities and relationships.
- Click Select All to select all entities and relationships.
- Select records in the entity or relationship type sublayer record table.
- Hold the Ctrl key and click selected entities and relationships on the canvas to unselect them.

- From the Context Toolbar, click Add Selection To .
- Click the appropriate option to add a knowledge graph layer to the map.
- Under Add to new..., click Map to create a map in the project.
- Under Add to existing..., click the name of an existing map.
- Under Add to new..., click Map
Add a knowledge graph layer from a map
After you create a map from an investigation's knowledge graph, you can add entities and relationships from the map to another map.
- Select the entities and relationships in the map that you want to add to the new map.
- Hold the Ctrl key and click the entities and relationships.
- Select records in the entity or relationship type sublayer record table.
- Hold the Ctrl key and click selected entities and relationships on the canvas to unselect them.

Toggle visibility of knowledge graph layers and sublayers
You can show or hide the knowledge graph layer and entity type and relationship type sublayers on a map.
- Click Options
next to the layer in the Map Contents pane. - Click Toggle visibility
to show or hide the knowledge graph layer and its sublayers.
Rename a knowledge graph layer or sublayers
A knowledge graph layer and its sublayers can be renamed in the map. Changing the name will only change the display name of the layer in the map contents pane of the current map. It will not change the layer's name across other maps in the project, or the name of the entity type or relationship type the layer represents.
- Click Options next to the layer in the Map Contents pane.
- Click Rename
.The rename dialogue appears.
- Enter the new layer name and click OK.
Remove knowledge graph records from a map
Entities and relationships can be removed from a map. Removed records will remain in other maps, link charts, and data cards in the project.
Note:
You cannot remove entities or relationships from a map if the entire knowledge graph was directly added to the map from the knowledge graph view. If an entire entity type or relationship type is added to a map from a knowledge graph view, individual records of this type cannot be removed from the map.
- Select the entities and relationships you want to remove from the map
- Hold the Ctrl key and click the entities and relationships.
- Select records in the entity or relationship type sublayer record table.
