title: Seaborn violin plot for pandas data
body: <p>I have a pandas dataframe heights_table with following info:
  Columns: Age, Height. Rows: each person in data set</p>
  
  <p>I want to generate a seaborn violin plot from this data. On the x-axis I want range of ages, and on the y axis, I want a 'blob' of height distributions for each of these ages. I know how to do a boxplot for this:</p>
  
  <pre><code>heights_table.boxplot(by='age')
  </code></pre>
  
  <p>How can I do a violin plot in seaborn for this? I have tried to read documentation <a href="http://seaborn.pydata.org/examples/elaborate_violinplot.html" rel="nofollow noreferrer">here</a>, but couldn't get it to work. Any help with be greatly appreciated!</p>
