<p>This example demonstrates the item type "background" when using groups.</p>
<ul>
  <li>Background items having a group are displayed in that group</li>
  <li>Background items without a group are spread over the whole timeline</li>
  <li>Background items with a non-existing group are not displayed</li>
</ul>
<div id="visualization"></div>
