title: How to visualize a graph/network in 3D
body: <p>I am working with networks which vertices are nodes of brain areas with specific coordinates. </p>
  
  <p>I need to visualize these networks in a 3D enviroments in order to improve the understanding of my results.</p>
  
  <p>Up to now I have tried to plot them using <code>rglplot</code> of <code>igraph library</code> in R, but the result is not so good in truth.
  Currently I am plotting them using projection on each pair of axis (XY, XZ, YZ).</p>
  
  <p>Futhermore I also have tried several tools like <code>gephi</code>, but it seems that 3D is not really supported.</p>
  
  <p>There is some tool or software for visualizing a network in a 3D space?</p>
