将Networkx图转换为具有其属性的数据帧

import networkx as nx
import pandas as pd

G = nx.Graph()
G.add_node(1, color='red', size=10)
G.add_node(2, color='blue', size=20)
G.add_edge(1, 2, weight=0.5)

df_edges = nx.to_pandas_edgelist(G)

node_attrs = nx.get_node_attributes(G, 'color')

df_nodes = pd.DataFrame()
df_nodes['node'] = node_attrs.keys()
df_nodes['color'] = node_attrs.values()
