准备

Anaconda3中的Spyder
提前安装networkx、 matplotlib

提示：以下是本篇文章正文内容，下面案例可供参考

一、无向图

代码如下（示例）：

import networkx as nx 
import matplotlib.pyplot as plt
import csv
 
with open('node-8.csv','rt') as csvfile:
	reader = csv.DictReader(csvfile)
	column = [row['b'] for row in reader]
#print (column)

 
 
 
edge = []
with open('edge-8.txt','r') as f:  
	data = f.readlines()  
	for line in data:
		#print (line)
		line = tuple(line.replace('\r','').replace('\n','').replace('\t','').split(','))
		edge.append(line)
#print (edge)

 
 
G = nx.Graph()
#G.add_nodes_from(id_tag)
G.add_edges_from(edge)
 
 
nx.draw_networkx(G,pos=nx.spring_layout(G),node_size=10,node_shape='o',width=0.3,style='solid',font_size=8) 


plt.show()

二、有向图

代码如下（示例）：

import networkx as nx 
import matplotlib.pyplot as plt
import csv
 
with open('node-8.csv','rt') as csvfile:
	reader = csv.DictReader(csvfile)
	column = [row['b'] for row in reader]
#print (column)

edge = []
with open('edge-9.txt','r') as f:  
	data = f.readlines()  
	for line in data:
		#print (line)
		line = tuple(line.replace('\r','').replace('\n','').replace('\t','').split(','))
		edge.append(line)
#print (edge) 
 
G = nx.DiGraph()
#G.add_nodes_from(id_tag)
G.add_weighted_edges_from(edge)
 
nx.draw_networkx(G,pos=nx.spring_layout(G),node_size=20,node_shape='o',width=1,style='solid',font_size=8) 

plt.show()
