title: Set default scale in vis js network
body: <p>I am using vis.js library to create a network topology. After I create the network using:</p>
  
  <pre><code>network = new vis.Network(container, data, options);
  </code></pre>
  
  <p>where container is the <code>canvas</code> on which I am drawing.</p>
  
  <p>data : </p>
  
  <pre><code>{
      nodes: Nodes,
      edges: Edges
  };
  </code></pre>
  
  <p>options : </p>
  
  <pre><code>{ 
      autoResize: true,
      nodes: {
          shape: 'image',
          size:  25,
          font: {
              size: 16,
              color: 'darkbrown'
          },
          borderWidth: 0,
          shadow: true
      },
      edges: {
          smooth: {
              forceDirection: "none"
          }
      },
      physics: {
          forceAtlas2Based: {
              springLength: 80,
              springConstant: 0.27
          },
          minVelocity: 0.75,
          solver: "forceAtlas2Based",
          timestep: 0.34
      },
      layout: {
          randomSeed: undefined
      },
      interaction: {
          hover: true
      }
  }
  </code></pre>
  
  <p>After it is drawn the default scale(1) is very large with respect to my canvas. I want to resize the scale. I have tried this way :</p>
  
  <pre><code>network = new vis.Network(container, data, options); //network is drawn
  
  var scaleOption = { scale : 0.5 }; -(1) 
  
  network.moveTo(scaleOption); -(2)
  </code></pre>
  
  <p>It doesn't work this way. However, if (1) and (2) are fired inside a particular event say : </p>
  
  <pre><code>network.on("click",function(params) {
  
      var scaleOption = { scale : 0.5 };
      network.moveTo(scaleOption);
  }); 
  </code></pre>
  
  <p>It works. I need to set the scale right at the beginning, i.e. right after topology is drawn(before the occurence of any such event). <code>AfterDrawing</code> event is continuously fired after the topology is drawn, so that fails too. Any way to resolve this?</p>
