如何使用动态键从字典中动态获取值并将其绘制到DataFrame？

data = {'key1': value1, 'key2': value2, 'key3': value3}

import pandas as pd
import matplotlib.pyplot as plt

df = pd.DataFrame.from_dict(data, orient='index', columns=['values'])

df.plot(kind='bar')
plt.show()

import pandas as pd
import matplotlib.pyplot as plt

data = {'key1': value1, 'key2': value2, 'key3': value3}

df = pd.DataFrame.from_dict(data, orient='index', columns=['values'])
df.plot(kind='bar')
plt.show()
