title: Link (via url) to specific node in infovis (jit) treemap
body: <p>Any infovis toolkit users out there? Would surely appreciate your help.</p>
  
  <p>I'm wondering if there's a way to link to a specific node via a standard href or some other method.</p>
  
  <p>Specifically, I'd like to retain the current node that the user is viewing while switching to a different view (link to a different set of data for the same entities). </p>
  
  <p>I've appended the current node to an HTML element (a div on the same page, easy enough) but can't find anything in the documentation about targeting a specific node via link.</p>
