If you use mvc_extjs you can do this like this:

Write a Controller Action which assigns the used objects to your View-Layer

Write a ViewHelper that converts the objects into the correct json 
representation that is understandable by the extjs tree.

To fetch the right URL inside your JavaScript-Code you can use the 
SettingsViewHelper contained in mvc_extjs (at the moment only in the 
view-branch, i think).

Inside the action that draws your module/plugin do something like this:

$treeDataUrl = 
$this->uriBuilder->uriFor('treemapactionname','treemapactionsnamecontrollername');
$settings = array(
   'treeDataUrl' => $treeDataUrl,
);
$this->view->assign('settings',$settings);

Access the url in JavaScript like this:

url: YourExtname.module/pluginname.Settings.treeDataUrl,
