Very cool. Two small suggestions: it would be marginally easier to read if you could use the teams’ colours for the bubbles on the chart, and I think the “winning points” deserves some text in the main circle rather than just being in the legend (you could do it subtly by marking the start of bonus points).
Would you be OK with me reposting this to 606v2 and Facebook? I have friends on both who would really enjoy this. How would you like it attributed?
