Importing STIX JSON Data in Neo4j

Hello

I am just looking for some general guidance/suggestions/resources on how I'd go about generating a graph from a STIX JSON file? A sample STIX JSON file here: https://oasis-open.github.io/cti-documentation/examples/identifying-a-threat-actor-profile

The graph nodes and relationships are contained within the same JSON file. I would appreciate any suggestions on the best way to split the objects/nodes from the relationships.
