title: Python Seaborn: How to add mean into boxplot visualization?
body: <p>I was able to visualize my data in a boxplot using Seaborn.</p>
  
  <pre><code>sns.boxplot( x=df['Score'].astype('float'), y=df['Group'] )
  </code></pre>
  
  <p>The visualization shows me: all four quartiles, lower and upper whisker, and some outliers. How can I also add the Mean line into the boxplots? See current visualization (without mean).</p>
