Load csv file and create nodes and reletionships - csv

Question

I've a csv file like the sample below and I want to import that into Neo4j and create nodes and relationships.
"N_ID","Name","Relationship","A_ID","Address"
"N_01","John Doe","resident","A_01","1138 Mapleview Drive"
"N_02","Jane Doe","resident","A_01","1138 Mapleview Drive"
"N_03","Randall L Russo","visitor","A_02","866 Sweetwood Drive"
"N_04","Sam B Haley","resident","A_03","152 Point Street"
"N_01","John Doe","mailing address","A_04",3490 Horizon Circle"
'm able to create nodes using the code below but i don't know how to create the relationships based on the csv file.
using PERIODIC COMMIT 1000
LOAD CSV WITH HEADERS FROM
‘File://contacts.csv' AS line
CREATE (:Person {ID:line.N_ID, name:line.Name})
I tried this, but it doesn't work.
CREATE (:Person {N_ID:line.N_ID, Name:line.Name})-[:line.Relationship]-> (:Address {A_ID:line.A_ID, Address:line.Address})
Please bear with me I'm new to Neo4j.

Install the apoc plugin and try this query:
USING PERIODIC COMMIT 1000
LOAD CSV WITH HEADERS FROM 'file://contacts.csv' AS line
MERGE (p1:Person {N_ID:line.N_ID})
ON CREATE SET p1.Name=line.Name
MERGE (a1:Address {A_ID:line.A_ID})
ON CREATE SET a1.Address=line.Address
WITH a1,p1,line
CALL apoc.merge.relationship(p1,line.Relationship,{},{},a1) YIELD rel
RETURN count(*);
