6 Nations 2021 Data Visualisation Project - Wales

Team: Wales 

Number of point scoring occasions: 46 

Number of players present for at least 1: 34 

Who scored the points?

Wales were another team where the kickers scored most of the points, but tries were reasonably evenly spread. 

When were the points scored? u9HTPe.png 
Wales's points were well spread over time 

Who scored when?

The spread of point scorers is borne out when the points per minute chart is coloured in by scorer. 

Who was present for more than one point scoring opportunity? u9VREs.png 

Louis Rees-Zammit and Justin Tipuric were the only Wales players present for all point-scoring moments.

The "who was on the pitch when for points" line chart shows Wyn Jones, Tomas Francis, Josh Navidi, Dan Biggar, Adam Beard and Jonathan Davies were players who were taken off before the end of matches. Certainly the times for Dan Biggar might explain why Callum Sheedy got so many points.

Who was on the pitch at the same time when points were scored?

Dendrogram

Heatmap

What's clear from the heatmap that wasn't clear from the dendrogram is that the Welsh team was very much Josh Adams, Dan Biggar, Adam Beard, Gareth Davies, Jonathan Davies (no relation), Louis Rees-Zammit, Justin Tipuric, Talupe Falatau, Alun Wyn Jones, Liam Williams, Wyn Jones (also no relation), Tomas Francis, Ken Owens, George North and Josh Navidi, with everyone else being brought on only if one of those needed to be taken off.

Matrix

The matrix view doesn't show the central fifteen as well as the heatmap, because it shows not just the "core" team, but also the players most likely to be subbed on because Wales scored a lot of points after minute ~65 when the substitutions occurred. 

This is a good example of why producing all three types of diagram is useful. Patterns may be more obvious in one view that the other two, and which of the three shows the patterns most clearly may change based on the underlying data.
