title: Cytoscape.js large data performance vs sigma.js
body: <p>I'm having a lot of trouble rendering a graph in cytoscape.js with ~1,000 nodes and ~5,000 edges (takes a very long time to render, once rendered impossible to interact with since browser is overloaded), however the same size graph appears to render fine and works well with sigma.js (<a href="http://sigmajs.org/" rel="noreferrer">http://sigmajs.org/</a>).</p>
  
  <p>I'm wondering why there is such a vast performance difference in the two libraries. I'd like to use cytoscape.js if possible since it seems much better documented and easier to work with, but I can only do so if it is able to work with sizable graphs in the browser.</p>
  
  <p>Any ideas?</p>
