title: Change line style circle segment Venn diagram
body: <p>I have this Venn diagram:</p>
  <pre><code>from matplotlib_venn import venn2, venn2_circles
  
  venn2(subsets = (30, 10, 5), set_labels = ('Group A', 'Group B'), set_colors=('r', 'g'), alpha = 0.5);
  venn2_circles(subsets = (30, 10, 5));
  </code></pre>

  <p>Is it possible to change the line style to dashed of just the circle segments where Group A and B overlap (i.e. the lines around the brown area)?</p>
