在Networkx中将piechart创建为节点

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)

node_attributes = {
    1: {'pie_data': [30, 40, 10, 20], 'labels': ['A', 'B', 'C', 'D']},
    2: {'pie_data': [10, 20, 30, 40], 'labels': ['E', 'F', 'G', 'H']}
}
nx.set_node_attributes(G, node_attributes)

pos = nx.spring_layout(G)

nx.draw_networkx_nodes(G, pos)
nx.draw_networkx_edges(G, pos)

for node, data in G.nodes(data=True):
    pie_data = data['pie_data']
    labels = data['labels']
    plt.pie(pie_data, labels=labels)
    plt.gca().set_aspect('equal')
    plt.gca().text(pos[node][0], pos[node][1], node, ha='center', va='center')

plt.axis('off')
plt.show()
