title: Programmatically create Venn diagrams at scale?
body: <p>I would like to create a Venn Diagram like the following:
  <a href="https://i.stack.imgur.com/3t5M3.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3t5M3.png" alt="enter image description here"></a></p>
  
  <p>The challenge is to have the circles and intersections with the right proportions. That is:</p>
  
  <ul>
  <li>Group 1 should be 15% of the universe, group 2 83%, and group 3 30%. </li>
  <li>The intersection between G1 G2 and G3 should be 7% of the universe</li>
  <li>etc</li>
  </ul>
  
  <p>Is there a way of doing this? This is what I have right now:</p>
  
  <pre><code>    library(VennDiagram)
  
      grid.newpage()
  
  
      draw.triple.venn(area1 = 15, area2 = 83, area3 = 30, n12 = 13, n23 = 28, n13 = 7, 
                       n123 = 7, category = c("Group 1", "Group 2", "Group 3"), lty = "blank", 
                       fill = c("skyblue", "pink1", "mediumorchid"))
  </code></pre>
