Construct 4 seaborn bar graphs from these data: 1) df1['city'].value_counts() 2) df2['hotel'].value_counts() 3) df2['date'].value_counts() 4) df2['rating'].value_counts()

def bar_graphs(df1, df2):
    plt.figure(figsize=(15,7))
    plt.subplot(2,2,1)
    sns.barplot(df1['city'].value_counts().index, df1['city'].value_counts().values)
    plt.xticks(rotation=40)
    plt.title('City')
    
    plt.subplot(2,2,2)
    sns.barplot(df2['hotel'].value_counts().index, df2['hotel'].value_counts().values)
    plt.xticks(rotation=40)
    plt.title('Hotel')
    
    plt.subplot(2,2,3)
    sns.barplot(df2['date'].value_counts().index, df2['date'].value_counts().values)
    plt.xticks(rotation=40)
    plt.title('Date')
