title: Plot a pandas categorical Series with Seaborn barplot
body: <p>I would like to plot the result of the <code>values_counts()</code> method with <code>seaborn</code>, but when I do so, it only shows one of the variables.</p>
  
  <pre><code>df = pd.DataFrame({"A":['b','b','a','c','c','c'],"B":['a','a','a','c','b','d']})
  counts = df.A.value_counts()
  sns.barplot(counts)
  </code></pre>

  <p>I want a barplot showing heights of <code>'a' = 1, 'b' = 2, 'c' = 3</code></p>
  
  <p>I've tried renaming the index and passing in <code>x</code> and <code>y</code> parameters, but I cant' get it to work.</p>
