有没有办法将JSON格式的单节点/边添加到networkx图中？

{
  "id": "node1",
  "label": "Node 1",
  "color": "red"
}

import networkx as nx
import json

# 解析JSON数据
json_data = '{"id": "node1", "label": "Node 1", "color": "red"}'
node_data = json.loads(json_data)

# 创建一个空的networkx图
G = nx.Graph()

# 添加节点到图中
G.add_node(node_data['id'], label=node_data['label'], color=node_data['color'])

{
  "source": "node1",
  "target": "node2",
  "weight": 0.5
}

import networkx as nx
import json

# 解析JSON数据
json_data = '{"source": "node1", "target": "node2", "weight": 0.5}'
edge_data = json.loads(json_data)

# 创建一个空的networkx图
G = nx.Graph()

# 添加边到图中
G.add_edge(edge_data['source'], edge_data['target'], weight=edge_data['weight'])
