Women's World Cup 2023 - Last 16 Network Diagrams

The first set of diagrams (https://fulltimesportsfan.wordpress.com/2023/07/22/womens-world-cup-2023-group-stage-network-diagrams/) was remarkably good at predicting the outcome of the group stages. 

The 3/16 that I didn't predict were Canada, although I did say group A would be tight, Italy, because they confounded me (again) and Germany, but I don't think anyone guessed that Germany would collapse like that. Definitely not German colleague who started a meeting with "please no jokes". 

To an extent, I think both Italy and Germany's closeness to the tight group at the bottom of the previous diagram was what meant I thought they'd go through when reading the diagram. 

With half the teams eliminated, the network diagram now looks like this. Last-16-not-labelled Last-16-labelled Much like Eurovision, there's a European and Australian cluster, which means the "central weight" of the diagram is not in the middle. 

That means that saying that either Leicester or the Chicago Red Stars are the club team closest to the centre, and either England or Nigeria are the national team closest to the centre doesn't give as much information as usual. 

The club teams with the most representatives left are Barcelona (with 15), Manchester City (with 13) and Paris Saint-Germain and Real Madrid (with 12 each). Manchester City and Real have crept up by not losing players, while other teams did. 

The community view looks like this: Last-16-Community-not-labelled Last-16-Community-labelled One day I'll figure out how to stop Gephi from cutting off the edges of the labels when the exceed the edges of the diagram. 

There are still three multi-team clusters, they are: 
England and Australia 
Denmark and Norway 
France and Netherlands 

These were also clusters in the first set of diagrams, with the change being that Sweden has moved out of the England and Australia cluster. 

While some of the eliminations were relatively straightforward to predict, the last 16 provides a number of games where "football knowledge" suggests one winner, and the diagram another. They are: Switzerland vs Spain - football knowledge says Spain, the diagram is unclear 
Netherlands vs South Africa - knowledge and diagram say Netherlands 
Japan vs Norway - knowledge says Japan, diagram says Norway 
Sweden vs United States - knowledge says United States, diagram says Sweden (US have been an outlying team, even when they win [https://fulltimesportsfan.wordpress.com/2019/07/01/womens-world-cup-semifinals/] so I think this might be one of the times when their is a weakness of the diagram based on circumstance. 
Australia vs Denmark - Ooooh, that's down as either way whichever method you look at it. 
France vs Morocco - knowledge and diagram say France, goalie hopefully says no (although I am happy with either team winning because I <3 renard="" wendi="">England vs Nigeria - knowledge and diagram says England Colombia vs Jamaica - knowledge says Colombia, diagram says Jamaica 

So this should be a good test of the underlying theory. 
(Even if it's wrong, I'll still keep making the diagrams because they're so pretty)
