title: Motion in drilldown bubble chart Highcharts
body: <p>I have created a drilldown for bubble chart. data for this drilldown is like:</p>
  
  <pre><code>drilldown: {
          series: [{
              id: 'animals',
              data: [
                  ['Cats', 5],
                  ['Dogs', 2],
                  ['Cows', 1],
                  ['Sheep', 2],
                  ['Pigs', 1]
              ]
          }, {
              id: 'fruits',
              data: [
                  ['Apples', 4],
                  ['Oranges', 2]
              ]
          }, {
              id: 'cars',
              data: [
                  ['Toyota', 4],
                  ['Opel', 2],
                  ['Volkswagen', 2]
              ]
          }]
      }
  </code></pre>
  
  <p>can i use data in sequence for drilldown for eg: 
  id:animals data will be so when i scroll horizontal datapoints for Cats will render one by one.</p>
  
  <pre><code>data: [
                  ['Cats', [5,1,2,3,4]],
                  ['Dogs', [2,1,5,6,7]]
              ]
  </code></pre>
