Popup drilldown visualisations

It would be great if we could define visualisations on a page as popup drilldown visualisations.  The drilldown would not be visible initially, then when you mark a visualisation you would have an option apear in a menu, to select the drill down visualisation required (if only one drill down available, the user will not be asked).

When a user makes a choice, the drill down visualisation appears, free floating above the other visualisations.

This would enable stacked, three dimensional dashboards, and would enable users to select the drill down visualisation they want to appear...instead of the drill down being hard coded on the page, taking up screen real estate.
