For the data skills test I accessed the Guardian's data store and selected some information to use. I chose the data which displayed the medals won by nations at the Winter Olympic Games. This data stood out for me because I thought that it could be represented well in a bar chart and I found the information interesting.
The Winter Olympics began in 1924 and since then there have been 22 Winter games and 44 nations have won medals. The chart above shows the top 10 nations to win medals at the Winter Olympics and allows you to see the ratio of different medals each country has won. The bar charts shows us that USSR/Russia has won 281 gold medals, far more than any other country, but is third when all medals are taken into account. All countries on this list have mountainous regions which shows that this is a clear advantage when competing at the Winter Olympics.
