title: swarmplot with hue affecting marker beyond color
body: <p>I'm trying to make my swarmplot easier to read in black&amp;white and for people that are color-blind, by having the hue affect not just the color but also another geometrical aspect of the marker.</p>
  <h2>MWE</h2>
  <pre><code>import seaborn as sns
  import matplotlib.pyplot as plt
  sns.set(style=&quot;whitegrid&quot;)
  tips = sns.load_dataset(&quot;tips&quot;)
  
  fig, ax = plt.subplots(1,1)
  ax = sns.swarmplot(x=&quot;day&quot;, y=&quot;total_bill&quot;, hue=&quot;sex&quot;,data=tips,size=8,ax=ax)
  plt.show()
  </code></pre>
  <h2>Result</h2>
