It is definitely not one of the most sophisticated visualizations out there, but it somehow competes with the likes of How Does 200 Calories Look Like, How Much Sugar is in Your Food? and What the World Eats.
Here, How Much Does Beer Consumption Vary by Country [snippets.com] displays the relative beer consumption per person for a collection of countries (although some notorious beer guzzling countries seem to be missing). According to the graph, there seems to be huge variations in consumption by country: the average person in the Czech Republic, for example, consumes about seven times as much beer as the average Chinese person.
The chart is not all that complicated, but I can imagine they had fun creating it.
