      Run below UQLs one by one in an empty graphset to create graph data:
      create().node_property(@default, "name").node_property(@default, "lat_long", point)
      insert().into(@default).nodes([{_id:"L001", _uuid:1, name:"New York", lat_long:point({latitude:40.7, longitude:-74.0})}, {_id:"L002", _uuid:2, name:"Paris", lat_long:point({latitude:48.5, longitude:2.2})}, {_id:"L003", _uuid:3, name:"Sydney", lat_long:point({latitude:-33.9, longitude:150.9})}, {_id:"L004", _uuid:4, name:"Beijing", lat_long:point({latitude:39.9, longitude:116.3})}])
      

      Comman Usage

      Exalmple: Direct calculate, return in kilometers

      find().nodes({name in ["New York", "Paris"]}) as a
      find().nodes({name in ["Sydney", "Beijing"]}) as b
      return table(a.name, b.name, distance(a.lat_long, b.lat_long)/1000)
      

      |  a.name  | b.name  | distance(a.point, b.point)/1000 |
