好的,这个问题可以直接回答。你可以使用Python中的networkx库来计算节点度取对数,然后使用matplotlib库进行可视化。以下是示例代码:
```python
import networkx as nx
import matplotlib.pyplot as plt
# 创建一个无向图
G = nx.Graph()
# 添加节点
G.add_nodes_from([1, 2, 3, 4, 5])
# 添加边
G.add_edges_from([(1, 2), (1, 3), (2, 3), (3, 4), (4, 5), (5, 1)])
# 计算节点度取对数
log_degrees = [nx.degree(G, node) for node in G.nodes()]
log_degrees = [0 if degree == 0 else round(nx.degree(G, node), 2) for node, degree in nx.degree(G)]
log_degrees = [0 if degree == 0 else round(math.log(degree), 2) for degree in log_degrees]
# 绘制可视化图表
plt.scatter(list(G.nodes()), log_degrees)
plt.xlabel('Node')
plt.ylabel('Log Degree')
plt.title('Log Degree Distribution')
plt.show()
```
希望这能帮助到你!
