title: VISJS: Changing the distance on how far nodes are spaced out
body: <p>I am using vis.js network to display nodes on a graph however I am interested in changing on how the spacing is displayed. When a node is clicked, it's neighbors are displayed.</p>
  
  <p>I noticed that when there are already a lot of nodes and more is to be displayed, the spacing gets huge. How can I reduce the spacing? When I turn on physics, gravity brings it closer but I prefer gravity to be off.
