Intra-team comparison: the dots show the position of the two drivers ("driver 1" in the team is blue the "second" driver s orange; the bar shows the difference between positions in the team. Bar to the left of the centre line shows that driver 1 was higher placed):
As a side-effect, the lack of a green bar denotes that at most only one car finished for the team. The chart therefore immediately makes it clear that Ferrari had good reliability, but the McLarens had quite a few races without a double finish. ALO and VET are also seen to dominate their respective team rankings. HUL has had a good run in his team in the latter part of the season.
Here's another take on that chart - but this time we order the x-axis for classification so that 1st is at x=23 (i.e. better placed is further to the right; winer is extreme right).
Reasons for non-finishes (no data for United States?):

Here's a close-up of fast pit stops by driver number:
