如何创建某个单词在一列中出现的次数直方图？

import matplotlib.pyplot as plt

# 数据准备
text_data = [
    "This is a sample sentence.",
    "Another sentence for testing.",
    "A third sentence to count words."
]

# 单词提取
word_list = []
for sentence in text_data:
    words = sentence.split()
    word_list.extend(words)

# 统计频次
word_count = {}
for word in word_list:
    if word in word_count:
        word_count[word] += 1
    else:
        word_count[word] = 1

# 绘制直方图
words = list(word_count.keys())
counts = list(word_count.values())

plt.bar(words, counts)
plt.xlabel('Words')
plt.ylabel('Frequency')
plt.title('Word Frequency Histogram')
plt.xticks(rotation=90)
plt.show()
