    The matplotlib.pyplot.plot() function is a versatile tool for creating 2D visualizations such as line graphs, scatter plots, and more. It allows customization of line styles, markers, and colors, making it ideal for plotting mathematical functions or datasets.

    Example – Plotting a Quadratic Function:

    import matplotlib.pyplot as plt
    import numpy as np

    # Define the function
    def f(x):
    return x ** 2

    # Create x and y values
    x = np.linspace(-5, 5, 1000)
    y = f(x)

    # Plot the function
    plt.plot(x, y, label='f(x) = x²', color='blue')
    plt.xlabel('X-axis')
    plt.ylabel('Y-axis')
    plt.title('Quadratic Function Plot')
    plt.legend()
    plt.grid(True)
    plt.show()

    This code uses NumPy to generate evenly spaced x values and applies the function element-wise. The plot() method then draws the curve with labels and a grid for clarity.

    Plotting Multiple Functions You can plot multiple functions on the same axes by calling plot() multiple times before show():

    def g(x):
    return 5 * np.sin(x)

    x = np.linspace(-5, 5, 1000)
    plt.plot(x, f(x), label='x²', color='blue')
    plt.plot(x, g(x), label='5sin(x)', color='red', linestyle='--')
    plt.title('Multiple Functions')
    plt.legend()
    plt.show()
    Copied!
    What is Matplotlib Pyplot?
    matplotlib.pyplot is a collection of functions that make matplotlib work like MATLAB. Each pyplot function makes some change to a figure: e.g., creates a figure, creates a plotting area in a figure, plots some lines in a plotting area, decorates the plot with labels, etc.
