The generated image is too small and cannot clearly see the connections between nodes. It is too dense. I hope there can be a solution

# _*_ coding:utf-8 _*_
import matplotlib.pyplot as plt
import networkx as nx

G = nx.DiGraph()
#加载文件中边的关系
with open('bigdata.txt') as f:
    lines = f.readlines()
mylist = [line.strip().split() for line in lines]  

pos =nx.spring_layout(G)

outlist = []
for i in range(len(mylist)):
    a = mylist[i][0]
    for j in range(len(mylist[i])-1):
        outlist.append([a, mylist[i][j+1]])

#加载边
G.add_edges_from(outlist)
nx.draw(G, with_labels=True, node_size=200,width=0.3, node_color='r', alpha = 0.7, edge_color='black',edge_vmin=2,edge_vmax=3)

plt.savefig('test1.png')
plt.show()

It is recommended to use d3py for network diagrams, or set the canvas size of matplotlib
