I found solution in this link useful to me for building my graph - https://community.neo4j.com/t/import-nodes-from-recursively-structured-json/11704
I was able to build the graph with the help of above mentioned link. I used the query given below.

WITH 'file:///part-of-VTree.json' AS json_file
CALL apoc.load.json(json_file,"..FileId") YIELD value AS result WITH json_file, result.result AS keys UNWIND range(0,size(keys)-1) AS i CALL apoc.load.json(json_file,"..[?(@.FileId == '" + toString(keys[i]) + "')].ChildNodes[*].FileId") YIELD value AS children
WITH keys[i] AS parent_key, children.result AS children
MERGE (parent:GroupNode {name: parent_key})
WITH parent, children
UNWIND children as child_key
MERGE (child:GroupNode {name: child_key})
MERGE (child)-[:CHILD_OF]->(parent)
RETURN *

This created a graph with nodes having "FileId" mentioned on it , as I was giving "FileId" as "name" property. When I change my query as below

WITH 'file:///part-of-VTree.json' AS json_file
CALL apoc.load.json(json_file,"..FileId") YIELD value AS result WITH json_file, result.result AS keys UNWIND range(0,size(keys)-1) AS i CALL apoc.load.json(json_file,"..[?(@.FileId == '" + toString(keys[i]) + "')].ChildNodes[*].FileId") YIELD value AS children
WITH keys[i] AS parent_key, children.result AS children
MERGE (parent:GroupNode {Fid: parent_key})
WITH parent, children
UNWIND children as child_key
MERGE (child:GroupNode {Fid: child_key})
MERGE (child)-[:CHILD_OF]->(parent)
RETURN *

It gives me a graph with nodes which has nothing mentioned on it. Earlier I was getting nodes with "FileId" mentioned on it.
what I want is nodes with "FileName" mentioned on it and "FileId" as its property.

With my current query I am not able to set properties for my node. Is there any way to set properties for my node and display "FileName" on nodes. "FileName" is not always unique so I can't create graph by extracting all "FileName" instead of "FileId".
"FileId" is always unique in my case.

Can anyone help me in some way to get my desired result. I need some help.
Thanks in advance!

I got it solved. This is the query I used to set properties for the nodes:

WITH 'file:///part-of-VTree.json' AS json_file
CALL apoc.load.json(json_file,"..FileId") YIELD value AS result WITH json_file, result.result AS keys UNWIND range(0,size(keys)-1) AS i CALL apoc.load.json(json_file,"..[?(@.FileId == '" + toString(keys[i]) + "')].ChildNodes[].FileId") YIELD value AS children
CALL apoc.load.json(json_file,"..[?(@.FileId == '" + toString(keys[i]) + "')].FileName") YIELD value AS rname CALL apoc.load.json(json_file,"..[?(@.FileId == '" + toString(keys[i]) + "')].ChildNodes[].FileName") YIELD value AS cname
WITH keys[i] AS parent_key, children.result AS children, rname.result AS rn, cname.result AS cn
MATCH (n {name:parent_key})
WITH n, children,rn,cn
UNWIND children AS child_key
OPTIONAL MATCH (n)-[:CHILD]->(m {name:child_key})
WITH n, rn, cn, collect(m) AS siblings
UNWIND range(0,size(rn)-1) AS k
SET n.label=toString(rn[k])
With cn,siblings
UNWIND range(0,size(cn)-1) AS j
FOREACH(j IN range(0, size(siblings)-1) |
FOREACH (p1 in [siblings[j]] |
Set p1.label=toString(cn[j])
))
RETURN *

Hope this would help someone.
