You can toggle between the grouped and stacked bar displays and sort the groups by avg. ranking or alphabetically. It could definitely still use refinement (e.g., more info on demand when hovering over bars, y-axis gridlines, etc.), but hopefully it’s a good start. I made it with d3.js, and you can explore the code that generates it here.
A few key takeaways from the graphic:
Spain has the highest ranking by far, and Group B has a crazy big skill spread, with the best (Spain) and worst (Australia) teams in it
Group G is strong all around, which gives it the edge over B in terms of average team ranking per group (as seen in stacked view)
Among the top three teams in a group, there’s even more parity in Group D; Uruguay, Italy, and England are all within 100 points of each other
Argentina (and Belgium) have fairly easy roads out of group stage
Can’t wait for the games to get started in June. Go USA!
