What are contour plots and how are they used?

Contour plots are graphical representations of three-dimensional data in two dimensions, using contour lines to connect points of equal value. They are commonly used in fields like meteorology, geography, and engineering to visualize data such as temperature, elevation, or pressure.

Can you give me an example of where contour plots are applied?

Sure! One common application is in meteorology, where contour plots are used to display weather patterns, such as isotherms for temperature or isobars for pressure, helping meteorologists analyze and predict weather changes.

How do I create a contour plot in Python?

You can create a contour plot in Python using libraries like Matplotlib or Seaborn. For example, using Matplotlib, you can use the contour function to plot your data. Would you like a code snippet?

Yes, please provide a code snippet!

Here's a simple example using Matplotlib:

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(-5, 5, 100)
y = np.linspace(-5, 5, 100)
X, Y = np.meshgrid(x, y)
Z = np.sin(np.sqrt(X**2 + Y**2))

plt.contour(X, Y, Z)
plt.title('Contour Plot Example')
plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.colorbar()
plt.show()
