title: How to adjust the position of circles when plotting venn diagram
body: <p>I wanted to plot the venn diagram with two sets in which one set falls completely within another. I could draw a diagram with R package <code>Venndiagram</code> like this </p>
  
  <p><img src="https://i.stack.imgur.com/U1J4r.png" alt="enter image description here"></p>
  
  <pre><code>library(VennDiagram)
  grid.newpage();
  venn.plot &lt;- draw.pairwise.venn(area1 =467 ,area2 =273 ,cross.area = 273,
  category = c("Set1", "Set2"),fill = c("darkorange", "dodgerblue1"),
  lty = rep("solid", 2),lwd = c(2,2),col = c("black","black"),cex = 2,cat.cex = 2,cat.pos = c(310, 135),
  cat.dist = 0.09,cat.just = list(c(-1, -1), c(1, 1)),
  ext.pos = 30,ext.dist = -0.05,
  ext.length = 0.85,ext.line.lwd = 2,ext.line.lty = "dashed");
  grid.draw(venn.plot);
  </code></pre>
  
  <p>This may sound like esoteric tricks, but how to adjust the position of the circles, say, instead of two concentric circles, let the inner circle touch the the outer one?</p>
  
  <p>Something like <a href="https://i.stack.imgur.com/0fqwE.png" rel="nofollow noreferrer">this one here</a>. I added one non overlapping element. </p>
  
  <p>I could not find an argument in the <code>Venndiagram</code> package allowing me to adjust the position of the circles. </p>
