title: Add data labels to Seaborn factor plot
body: <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>
