How can I create a line plot using Matplotlib?

To create a line plot in Matplotlib, you can use the plot() function. Here's a simple example:

import matplotlib.pyplot as plt

x = [1, 2, 3, 4]
y = [10, 20, 25, 30]

plt.plot(x, y)
plt.title('Line Plot Example')
plt.xlabel('X-axis')
plt.ylabel('Y-axis')
plt.show()

What if I want to customize the line color and style?

You can customize the line color and style by adding parameters to the plot() function. For example:

plt.plot(x, y, color='red', linestyle='--')

This will create a red dashed line.

How can I add markers to the line plot?

You can add markers by using the marker parameter in the plot() function. For example:

plt.plot(x, y, marker='o')

This will add circular markers at each data point.

Can I save the plot as an image file?

Yes, you can save the plot using the savefig() function. For example:

plt.savefig('line_plot.png')

This will save the plot as a PNG file.
