如何使用此数据框绘制三维图形？

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D

# 创建数据框
data = pd.DataFrame({'x': [1, 2, 3, 4, 5],
                     'y': [2, 4, 6, 8, 10],
                     'z': [3, 6, 9, 12, 15]})

# 创建三维图形
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

# 绘制三维曲面图
ax.plot_surface(data['x'], data['y'], data['z'])

# 设置坐标轴标签
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')

# 显示图形
plt.show()
