title: Making igraph clearer to read
body: <p>I have a directed igraph with 69 vertices, shown below. It was plotted using the igraph package:</p>
  
  <pre><code>library(igraph)
  ig &lt;- graph.adjacency(data, mode="directed", weighted=TRUE) 
  plot(ig)
  </code></pre>
  
  <p>I'm looking to achieve the following 2 things:</p>
  
  <p>(a) Space the vertices out and maybe lengthen the edges to make it a little easier to read</p>
  
  <p>(b) In reality, my labels are longer. Is it possible to make a vertex bigger and the text smaller to accommodate this.</p>
  
  <p>Any ideas?  </p>
  
  <p>Here is my data: <a href="https://www.dropbox.com/s/rtedrd1x1duqllj/data.Rdata?dl=0" rel="nofollow noreferrer">https://www.dropbox.com/s/rtedrd1x1duqllj/data.Rdata?dl=0</a>  </p>
