推荐直接用graphviz画图。

networkx画图

备注：不推荐，复杂的图看起来有问题

安装networkx、matplotlib

画图

import networkx as nx
import matplotlib.pyplot as plt

G = nx.DiGraph()  # 创建一个有向图
G.add_node("A")  # 添加节点A
G.add_node("B")  # 添加节点B
G.add_node("C")  # 添加节点C

G.add_edge("A", "B")  # 添加从A到B的边
G.add_edge("B", "C")  # 添加从B到C的边
G.add_edge("C", "A")  # 添加从C到A的边

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

运行

graphviz画图

安装

brew install graphviz
pip install graphviz

画图

import graphviz
dot = graphviz.Digraph()

nodes = ['1', '2', '3', '4', '5', '6', '7', '8', '9']
deps = [
    ('1', '2'),
    ('2', '3'),
    ('3', '4'),
    ('4', '5'),
    ('5', '6'),
    ('6', '7'),
    ('7', '8'),
    ('8', '9'),
    ('9', '1'),
]

for node in nodes:
    dot.node(node, node)

for dep in deps:
    dot.edge(dep[1], dep[0])

dot.render('dag', view=True)

运行
