Chelsea and Everton the "most improved" while both having a generally awful start to the season is a fun indication of how useful xG is.
Except Everton have been pretty good and are easily the most underrated team in the leauge. I'd argue they were pretty unlucky and were shit aginst Luton which apparently is the only relevant game of the season for judging them on. If anything, their quality on the pitch compared with their xG is a lot more similar than when compared to how many points they've gained.
xG is worthless for you because you couldn't finish of a virgin who'd been edging for 8 hours.
Really?
The badges are large enough to be legible without being so large their crowd each other too much.
The line is obviously connecting 2 points, one being the badge, and the change in width tells you immediately that's it's a progression from the thin point to the thick one. They're also coloured well so you can immediately tell who is who.
There are lines on the background to help group without even using the axes.
