We do support multi-graphs but it's currently not possible to edit this column via the Data Laboratory.

Definition of done

• Edge kind is properly shown in the 'Edit' panel (under properties)
• Edge kind can be changed from the Data Laboratory
• Data Laboratory manipulators allow 'kind' to be edited (fill column with value, clear etc.)
• Does not show that column if the graph is not a multi-graph
• New column with Kind name can't be added if already present
• (Optional) Creating a Kind column as an option in the Merge Column menu
• When exporting via CSV, the 'Kind' column should be present when relevant

Notes

• In the Graph API, edge kind is named edge label.
• The edge kind type is defined in the graph configuration and can't be changed
