Tour de France: Top-five finishers by nationality for 100 years by James Fransham, Lloyd Parker, Robert Jones and Phil Kenny

On the centenary of the start of the Tour de France cycling race this year, we thought about how we could show how the nationalities of the winners changed over time. We chose to adopt a "pinwheel" technique to fit 100 years worth of top five finishers, using colour to depict nationality. The chart beautifully shows how, from a parochial race in 1913, more countries like Belgium and Italy had strong finishes until the Tour emerged as a truly global event.
