    Contour plots are a way to represent three-dimensional data in two dimensions using contour lines. These lines connect points of equal value, creating a map-like visualization. In Python, the matplotlib library provides a convenient way to create contour plots using the contour and contourf functions.

    Creating Contour Plots with Matplotlib

    To create a contour plot, you need three sets of data: X, Y, and Z. The X and Y arrays represent the coordinates, while the Z array contains the height values over which the contour is drawn. Here's a basic example:

    import matplotlib.pyplot as plt
    import numpy as np

    # Create data
    X, Y = np.meshgrid(np.linspace(-3, 3, 256), np.linspace(-3, 3, 256))
    Z = (1 - X/2 + X**5 + Y**3) * np.exp(-X**2 - Y**2)

    # Define contour levels
    levels = np.linspace(np.min(Z), np.max(Z), 7)

    # Create contour plot
    fig, ax = plt.subplots()
    ax.contour(X, Y, Z, levels=levels)
    plt.show()
