ModulNotFoundError matplotlib

[WicardBohnam]

I'm new to Python and have installed Python 3.12.3 with idle on Windows 10. Having had fairly good success with other scripts, I decided to try to code a simple plot from example, I believe I have installed matplotlib, but I get an error message "ModuleNotFoundError: No module named 'matplotlib'"
Filename scatter_plot.py
Thanks,
Here's the script:

import matplotlib.pyplot as plt
import numpy as np

# Fixing random state for reproducibility
np.random.seed(19680801)


N = 50
x = np.random.rand(N)
y = np.random.rand(N)
colors = np.random.rand(N)
area = (30 * np.random.rand(N))**2  # 0 to 15 point radii

plt.scatter(x, y, s=area, c=colors, alpha=0.5)
plt.show()
