有没有办法为nx添加箭头？在networkx中取胜？

import networkx as nx
import matplotlib.pyplot as plt

# 创建一个有向图
G = nx.DiGraph()

# 添加带有箭头的边
G.add_edge('A', 'B', arrowhead='->')

# 绘制图形
pos = nx.spring_layout(G)
nx.draw_networkx(G, pos, with_labels=True, node_size=500, node_color='lightblue', font_size=12, font_color='black', arrows=True)
plt.show()
