Read graph into NetworkX from JSON file

I have downloaded my Facebook data. I got the data in the form of JSON files.

Now I am trying to read these JSON files into NetworkX. I don't find any function to read graph from JSON file into NetworkX.

In another post, found the info related to reading a graph from JSON, where the JSON file was earlier created from NetworkX using json.dump().

But here in my case I have downloaded the data from Facebook. Is there any function to read graph from JSON file into NetworkX?

Unlike Pandas tables or Numpy arrays, JSON files has no rigid structure so one can't write a function to convert any JSON file to Networkx graph. If you want to construct a graph based on JSON, you should pick all needed info yourself. You can load a file with json.loads function, extract all nodes and edges according to your rules and then put them into your graph with add_nodes_from and add_edges_from functions.

For example Facebook JSON file you can write something like it:

import json
import networkx as nx


with open('fbdata.json') as f:
    json_data = json.loads(f.read())

G = nx.DiGraph()

G.add_nodes_from(
    elem['from']['name']
    for elem in json_data['data']
)
G.add_edges_from(
    (elem['from']['id'], elem['id'])
    for elem in json_data['data']
)

nx.draw(
    G,
    with_labels=True
)

And get this graph:
