IMO, the "only show text + links on hover" thing needs to go. If you absolutely must do something like this, please use faded-but-visible text instead of completely hiding it.

(It's also really annoying on mobile where you have to actively tap to show the links.)

EDIT: Reasoning: Does this page contain the information I need? I can't tell without apparently hovering over everything. (Plus, if I hover away from one of the 'graphs' it's easy to forget what was on there.)

Right, I nearly missed the fact that there were links - if my mouse pointer hadn't passed over one of the fields while going to the "close tab" button.

Right you are. It's the old interaction design adage, "put the knowledge in the world, not in the brain".

x1000. You can't use hover because of mobile.
