European Union as a country in Rio 2016

The Telegraph article EU puts itself at the top of Rio Olympics medal table shows an alternative version of the Olympic medals table with all medals awarded to the EU countries grouped together, originally published by This visualization reproduces the calculation, but you can also easily tweak it to see the alternative Brexit chart, or a chart for London 2012.

The summary counts only Gold medals and it groups the medals by event (so we only count one medal for team events where a large number of individuals were awarded a medal). This seems to be what MedalTracker does, but you can change the code to count raw kilograms of Gold if you wish!

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.
