title: Resize nodes in vis js which has label inside e.g. Circle, Box
body: <p>How to set size of shapes in vis js which can have label inside?
  e.g.</p>
  
  <p>Code1:</p>
  
  <pre><code>    shape: 'circle',
      color: {
          border: 'black',
          background: 'white'
      },
      borderWidth: 1,
      borderWidthSelected: 2,
  </code></pre>
  
  <p>in above Code1, if there is nothing in label to put in shape circle, then how i can increase/decrease the size of same.<br> If shape is anything for which label is put outside we can increase and decrease the size of icons. e.g.</p>
  
  <p>Code2:</p>
  
  <pre><code>    shape: 'icon',
      icon: {
          face: 'FontAwesome',
          code: '\uf1db',
          size: 100,
          color: '#000000'
      }
  </code></pre>
  
  <p>As in above Code2 for icon 'size' option is available.<br>Is there any way to use 'size' option in Code1?</p>
