如何在使用networkx模块在python中绘制图形时给出x和y标签？

import networkx as nx
import matplotlib.pyplot as plt

G = nx.Graph()

G.add_node(1)
G.add_node(2)
G.add_edge(1, 2)

pos = nx.spring_layout(G)  # 使用弹簧布局算法设置节点位置
nx.draw(G, pos)

labels = {1: 'Node 1', 2: 'Node 2'}  # 定义节点标签
nx.draw_networkx_labels(G, pos, labels)

edge_labels = {(1, 2): 'Edge Label'}  # 定义边标签
nx.draw_networkx_edge_labels(G, pos, edge_labels)

plt.show()
