The most basic unit of offence in hockey is the shot and so I have made a great many charts showing how efficiently teams generate shots in a wide variety of situations. For the purposes of making shot maps, I use "shot" to mean any unblocked shot; that is, a shot which is missed, saved, or scored. If I had access to shot location data for blocked shots I would almost certainly include them also, but I do not.
On the one hand, the Sharks had one of that season's better 5v5, offenses but in fact the number of excess shots is not very many. For instance, the red area in the slot is perhaps around 200 square feet (notice the reference circle for area in the bottom right) and so the excess shots from that area is about one per hour of 5v5 play. Such an advantage is non-trivial, of course, since such shots are dangerous, but one must also keep in mind that the spread of performance results in the NHL is quite small.
Because some of the later charts can be based on relatively few minutes, I decorate every shot map with the number of minutes shown; for a team in a full season the number is very large.
I also make charts to show power-play shot rates; they are easy to distinguish from the 5v5 charts because of their different colour schemes: here pink/purple means "more than average", while green means "less than average". The notion of "average" here of course is 5v4 average, and the scale is also doubled, since the variance in power-play shot rates is larger than in 5v5 shot rates. In this example, Washington's extremely Ovechkin-dependent powerplay from 2017-2018 shows a heavy asymmetry, with a big hotspot from his usual "spot".
Finally, I also make charts for the shots allowed by a team while short-handed, with the same colourscheme as the power-play offence charts above: pink/purple for "more than average", green for "less than average". Here, New Jersey's penalty-kill from 2017-2018 allowed fewer shots than the league-average penalty-kill did from immediately in front of their net, with a small increase in shots in the high slot.
