title: How to modify the curvature of edge line in cytoscape.js?
body: <p>I want to modify the curvature of edge between two nodes.
  I know there is a function "curve-style". but as it says "The curving method used to separate two or more edges between two nodes".</p>
  
  <p>In my case, there is only one single edge between two nodes.</p>
  
  <p>Is there any way that I can define the curvature like in "curvature " property in cytoscape web?</p>
