Add data labels to Seaborn factor plot
<p>I would like to add data labels to factor plots generated by Seaborn. Here is an example: </p>

<pre><code>import pandas as pd
from pandas import Series, DataFrame
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
%matplotlib inline

titanic_df = pd.read_csv('train.csv')
sns.factorplot('Sex',data=titanic_df,kind='count')
</code></pre>

<p>How can I add the 'count' values to the top of each bar on the graph?</p>
