This field is necessary if you wish to use the Auras feature to visually group multiple nodes. Nodes with matching Aura IDs in this column will become a part of an aura, and all nodes within the same aura group will be encircled with a colorful area on the map. 

Once data has been added to this field, Format Visual tab will reveal Auras (General Settings) section for global aura settings, in addition to separate Aura X Configuration sections to apply visual customization to each aura group that you have included in this field. 

This visual supports up to nine aura groups, and this field must contain the specific aura IDs: “aura1”, “aura2”, “aura3”, “aura4”, “aura5”, “aura6”, “aura7”, “aura8”, and “aura9”.
