Hello Matplotlib

Let's start by importing the Matplotlib library. Open a new terminal and type:

python3

This will open a Python interpreter. Now, let's import the Matplotlib library:

import matplotlib.pyplot as plt

Now, let's create a NumPy array with 1000 values between 0 and 2π:

import numpy as np
x = np.linspace(0, 2*np.pi, 1000)

Now, let's create a plot and show it:

plt.plot(x, np.sin(x))
plt.show()
