Python 画关系网络图

年轻人，耗子尾汁

#使图表中的中文字符正常显示

#读取数据，含有关系1、关系2、权重三列

G = np.Graph()

for i in range(data.shape[0]):
    u,v,d = data.iloc[i,0],data.iloc[i,1],data.iloc[i,2]
    G.add_weighted_edges_from([u,v,d])

nx.draw_networks(G,with_labels = False,node_size = 10,style = 'dashed')
plt.savefig('关系网络.svg')
plt.show()
