Have some code that will build the tree in the order that I am looking for:

import json

data = json.load(open('x.json'))

class Node:
    def __init__(self, dct):
        self.id = dct['id']
        self.name = dct['name']
        self.parent = dct['parentId']
        self.children = []

def insert( tree, node ):
    if tree.id == node.parent:
        tree.children.append( node )
        return True
    for n in tree.children:
        if insert( n, node ):
            return True

def traverse( tree, pfx='' ):
    pfx = tree.name if not pfx else ' '.join((pfx, '>', tree.name))
    print( pfx )
    for n in tree.children:
        traverse( n, pfx )

tree = Node(
    {
        'id': "52ff2cfce4b0b193ed664d1a",
        'name': 'Cybersecurity',
        'parentId': None
    }
)
for k,v in data['businessModelInfo'].items():
    if not insert( tree, Node(v) ):
        print( v, "location not found" )

traverse( tree )
