In this viz, we take a look at the athletes that competed in the past 4 summer games.
The first tab compares the number of athletes that each country sends to the games. The slide bar is adjustable, so nations that only send 10 athletes can be compared to like similar nations and not be overshadowed by the larger nations.
The second tab shows the distance that athletes from each nation have had to travel to get to the games. Zooming in on Athens, which is surrounded by many other nations, really shows how international the Olympics really are.
