title: Annotate markers values on Seaborn line plot (sns)
body: <p>is there a way to annotate the markers value on a Seaborn line plot?</p>
  
  <p><strong>This is my actual line plot:</strong></p>
  
  <pre class="lang-py prettyprint-override"><code>a4_dims = (20, 10)
  fig, ax = plt.subplots(figsize=a4_dims)
  p1 = sns.lineplot(x='NBags', y='value', hue='variable', style="variable", markers=True, dashes=False, 
               data=pd.melt(df_knn1, ['NBags']))
  </code></pre>
