Exploring data: Graphs and numerical summaries

East Germany 10
France 52
Japan 43
South Korea 9
Soviet Union 73
Spain 10
Sweden 12
UK 41
USA 119
West Germany 23

You could scarcely have a more straightforward table than this, and yet it is by no means clear what is the most meaningful and appealing way to show the information.
