在networkx中绘制带标签的可读图

import networkx as nx
import matplotlib.pyplot as plt

G = nx.Graph()  # 创建无向图
# G = nx.DiGraph()  # 创建有向图

G.add_node("Node 1")  # 添加节点
G.add_node("Node 2")
G.add_edge("Node 1", "Node 2")  # 添加边

labels = {"Node 1": "Label 1", "Node 2": "Label 2"}  # 节点标签
edge_labels = {("Node 1", "Node 2"): "Edge Label"}  # 边标签

pos = nx.spring_layout(G)  # 设置节点位置
nx.draw_networkx_nodes(G, pos)  # 绘制节点
nx.draw_networkx_edges(G, pos)  # 绘制边
nx.draw_networkx_labels(G, pos, labels)  # 绘制节点标签
nx.draw_networkx_edge_labels(G, pos, edge_labels)  # 绘制边标签
plt.axis("off")  # 关闭坐标轴
plt.show()  # 显示图形
