Number of point scoring occasions: 32 ( It's deliberately phrased as number of point scoring occasions as, in this, a try, a conversion and penalties each count as one.)
Number of players present for at least 1: 27
Who scored the points?
Despite how heavily tilted that is to Owen Farrell, it's about what you'd expect, because, even without penalties, the person assigned kicking duties (normally the fly half), Owen Farrell in England's case, gets a chance to score after each try. So you expect them to have roughly as many point-scoring occasions as everyone else added together.
When were the points scored?
Here we have literally the only problem I've found, I can't convince the code to put points scored in minutes 0-9 ahead of the number 10. It's less of a problem with England, because there was only one points-scoring occasion before 10 minutes, but it's definitely a problem for Wales's data.
Who scored when?
The diagrams highlight the Farrell domination.
This is the % version of the same diagram - 
I think the not-percentage version is clearer.
Who was present for more than one point scoring opportunity?
For England, Tom Curry, Maro Itoje, Jonny May and Anthony Watson were present for all the point scoring moments.
This next diagram nicely shows which players tended to get subbed off due to the position they played
I'll get back to this in the final, future work section of the summary post, but I'd be really interested to see how this looks for something like rugby league where you have rolling substitutions (or, indeed ice hockey).
Who was on the pitch at the same time when points were scored?
Dendrogram
Heatmap
You can clearly see the Curry, Itoje, May and Watson cluster, but I am intrigued by the Genge, Stuart, Robson, Lawrence, Earl, George mini-cluster at the top of the diagram. I wonder if they're the ones that get subbed on to finish games.
Matrix of co-occuring players
The mini-cluster are also present in the matrix diagram, separate to the main cluster of players frequently on the pitch when England scored. There's a central 11 (Vunipola B, Curry, Itoje, Slade, Watson, Youngs B, May, Daly, Sinckler, Ford and Farrell), who also correspond with what I'd consider as Eddie Jones's core team from last year.
