one of graph visualization advantage is to be able to display A LOT of information and relations between them

I think Bloom does not help with that because of some layout choices I do not understand.

For example, why are layout algorithm spreading nodes so much apart , wasting so much space (read line in screen shot) when , on contrary, I wish nodes to be as grouped as possible so I can get the big picture of as much of them as possible while still being able to read node label.

I really do not see in what context so much space between nodes is useful

Also, selecting text x3 does not make any difference in zoom out, only cuts off more of the text in zoom in...
