[USER (data scientist)]: Awesome! Now, I was thinking, can we make a bar chart to show the number of laptops from Dell, HP, and Lenovo? Please generate and display a bar chart to visualize the number of laptops from Dell, HP, and Lenovo in the 'laptops_price' dataframe.
My template of code snippet is:

---BEGIN CODE TEMPLATE---

import pandas as pd
import pickle
import matplotlib.pyplot as plt 

laptops_price = pd.read_csv("laptops_price.csv")

# YOUR SOLUTION BEGIN:
<code1>
[GENERATE YOUR CODE]
</code1>
# YOUR SOLUTION END:

plt.savefig('./pred_result/bar_chart.png')
plt.show()

---END CODE TEMPLATE---

[YOU (AI assistant)]: Sure thing! We can use the matplotlib library to create a bar chart. Here's the code to make it happen:
