python matplotlib example

Here is an example of how to use matplotlib in Python to plot a simple line graph:

import matplotlib.pyplot as plt

# Create some sample data
x = [1, 2, 3, 4, 5]
y = [2, 4, 6, 8, 10]

# Create the plot
plt.plot(x, y)

# Add labels and title
plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.title('Sample Line Graph')

# Show the plot
plt.show()

This code will produce a simple line graph with x-values 1 to 5 on the x-axis and y-values 2 to 10 on the y-axis. The plot will have labels for the x and y axes and a title at the top. The `plt.show()` function is used to display the plot.
