Auras can be used to visually group multiple nodes regardless of their actual relationships. Nodes with matching aura IDs will be encircled by a colorful area. 

If you wish to assign the aura to the source node, this field must contain the ID of your aura. If you want to assign multiple auras to the same node, seperate aura IDs with a comma (for example: aura1, aura2, aura3). 

You can create up to nine different auras, and customize each aura’s color, opacity, title, and other settings in their Aura X Category sections within the Format Visual tab.
