Is there a reason that some icons of SE sites are not paired up neatly with their respective meta icon on SE Data Explorer, while the vast majority are? If not or if it is bypassable, I suggest the order be changed.
(Please ignore the fact that Stack Apps was erroneously included in a free-hand circle -- there is no meta site for it.)
Most notably, it is entirely unclear for a user why meta.tex.sx comes way before tex.sx, which is at the very end.
Related question that doesn't quite answer this one, if I understand correctly: What criterion is used to determine which Stack Exchange 2.0 sites are included in the data explorer?
