There is a data set regarding my consumption information in canteens of SUFE in April 2018, Download the data.json file. By Plotly or Matplotlib, please draw a histogram illustrating the frequencies of my visiting different canteens.

Sure, I can help you with that. However, I don't have access to your data.json file, so I'll use some sample data to illustrate the process. Here's an example code using Matplotlib:

import matplotlib.pyplot as plt
import numpy as np

# Example data
canteens = ['Canteen A', 'Canteen B', 'Canteen C', 'Canteen D']
visits = np.random.randint(1, 11, size=len(canteens))

# Create a bar chart
fig, ax = plt.subplots()
ax.bar(canteens, visits)

# Set chart title and axis labels
ax.set_title('Frequency of Visiting Different Canteens')
ax.set_xlabel('Canteens')
ax.set_ylabel('Visits')

plt.show()

This code generates a bar chart instead of a histogram, as it better represents the frequency of your visits to different canteens. You can modify the code to fit your specific data and preferences.
