i'm on chrome / firefox and it shows up as an occluded mess.
i think i'm seeing all the leaf nodes but not the intermediary nodes.
but I really want to see it so please fix :)
same here, see http://tinypic.com/r/2efkild/7
it also makes switching to this tab on firefox very slow, probably because you have a lot of javascript running there.
I'm on Safari and ditto.
I'm on Chrome and it looks great - but damn if I can see any reasonable clustering that makes any semantic sense to me.
on opera mini-Android, the browser hangs. Which is quite surprising, since Opera Mini pre-processes pages.
