Czech and Slovak Medalists of All Time

This visualization is another variation on "Individual Medalists of All Time", but rather than looking at medalists of all teams, it only looks at medalists from Czech Republic, Slovakia, Czechoslovakia and Bohemia which competed in Olympic games between 1900 and 1912 as an autonomous part of Austria-Hungary.

The list of teams included in the visualization can be easily modified, so if you are interested in another team (or multiple teams), you can just use "options" and modify the team list.

Rather than sorting the medalists by number of Gold medals (as the original visualization does), here we sort the medalists by the total number of medals. Again, this can also be changed in the "options".

Number of teams per Games

The visualization shows how the number of countries who participate in Olympics has been changing over the history of the Olympic games. The number is steadily growing, with the exception of 1980s when Western block and Eastern blocked countries boycotted games in USA and Soviet Union.
