创建一个空的无向图

G = nx.Graph()

添加节点

G.add_nodes_from([1, 2, 3, 4])

添加边

G.add_edges_from([(1, 2), (2, 3), (3, 4), (4, 1)])

绘制图形

pos = nx.spring_layout(G)
nx.draw(G, pos, with_labels=True, node_size=1500, node_color='skyblue', font_size=10, font_weight='bold', arrows=False)
plt.title("Simple Graph Example")
