body: <p>I'm trying to plot a seaborn.pairplot with small dots like this one:

  <p>But I get one with the markers much bigger and I can't find how to change their size in the documentation. My pairplot looks like this:</p>
  
  <p><a href="https://i.stack.imgur.com/QNLW8.png" rel="noreferrer"><img src="https://i.stack.imgur.com/QNLW8.png" alt="enter image description here"></a></p>
  
  <p>The code I'm using to plot is:</p>
  
  <pre><code>sns.pairplot(df, diag_kind='kde')
  sns.plt.show()
  </code></pre>
