使用python绘制3D散点图？

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

# 生成随机数据
np.random.seed(123)
n = 100
x = np.random.rand(n)
y = np.random.rand(n)
z = np.random.rand(n)

# 创建3D图形对象
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

# 绘制散点图
ax.scatter(x, y, z, c='r', marker='o')

# 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()
