从pandas df绘制x轴上的字数及其在y轴上的出现情况

import pandas as pd
import matplotlib.pyplot as plt

data = {'text': ['apple', 'banana', 'orange', 'grape', 'watermelon'],
        'count': [5, 6, 6, 5, 10]}
df = pd.DataFrame(data)

df['word_length'] = df['text'].apply(lambda x: len(x))

plt.bar(df['word_length'], df['count'])
plt.xlabel('Word Length')
plt.ylabel('Count')
plt.title('Word Length vs Count')
plt.show()
