title: How to increase space between edges (splines) and nodes in graphviz?
body: <p>I manually specified the starting position of every node and set splines=true.</p>
  
  <p>The resulting image appears as follows:</p>
  
  <p><img src="https://i.stack.imgur.com/E6qhe.png" alt="graph"></p>
  
  <p>The spline between 1031 and 1028 appears to touch nodes 1030 and 1029. I am just wondering if there's a way to increase the margin here. I have tried specifying esep="+3,3" to give a very high margin around nodes but the same graph is still output.</p>
