Node Self Link

Choose how the visual handles self-linking nodes. If the Source Nodes and Target Nodes fields contain matching node IDs,  the visual will treat it as a self-linking node, which means that the link will start and end at the same node. You can choose how such cases will be displayed on your graph:
  • Off (default): Self-linking connections will not be displayed. 
  • On: Self-linking connections will be displayed with a link that loops around the node.
