title: Seaborn Violin Plot from Pandas Dataframe, each column its own separate violin plot
body: <p>I have Pandas Dataframe with structure:</p>
  
  <pre><code>   A  B
  0  1  1
  1  2  1
  2  3  4
  3  3  7
  4  6  8
  </code></pre>
  
  <p>How do I generate a Seaborn Violin plot with each column as its own separate violin plot for side-by-side  comparison?</p>
