将csv文件转换为边和节点以创建和绘制networkx图

import pandas as pd
import networkx as nx
import matplotlib.pyplot as plt

df = pd.read_csv('data.csv')  # 替换为你的CSV文件路径
nodes = df['node'].unique()  # 获取唯一的节点列表

G = nx.Graph()

G.add_nodes_from(nodes)

edges = df[['source', 'target']].values  # 获取源节点和目标节点的边
G.add_edges_from(edges)

nx.draw(G, with_labels=True)
plt.show()
