准备模拟数据

# Using Chinese characters as column names
columns = ['A', 'B', 'C', 'D',
           'E', 'F', 'G', 'H']
# Since we cannot extract the actual data from the image, we will create scatter plots with mock data.
# Please note that the values used here are randomly generated and do not correspond to any real dataset.

# We'll use numpy to generate the random data
import numpy as np

# Number of observations
n = 50

# Mock data generation
np.random.seed(0)  # For reproducibility
