Between teaching two classes, and a seminar, and logging two coast-to-coast flights, I was able to find time to rethink the following chart from the Wall Street Journal: (link to article)

Uk_drinks

I like the right side of this chart, which helps readers interpret what the alcohol consumption guidelines really mean. When we go out and drink, we order beers, or wine, or drinks - we don't think in terms of grams of alcohol.

The left side is a bit clumsy. The biggest message is that the UK has tightened its guidelines. This message is delivered by having U.K. appear twice in the chart, the only country to repeat. In order to make this clear, the designer highlights the U.K. rows. But the style of highlighting used for the two rows differs, because the current U.K. row has to point to the right side, but not the previous U.K. row. This creates a bit of confusion.

In addition, since the U.K. rows are far apart, figuring out how much the guidelines have changed is more work than desired.

The placement of the bars by gender also doesn't help. A side message is that most countries allow men to drink more than women but the U.K., in revising its guidelines, has followed Netherlands and Guyana in having the same level for both genders.

After trying a few ideas, I think the scatter plot works out pretty well. One advantage is that it does not arbitrarily order the data men first, women second as in the original chart. Another advantage is that it shows the male-female balance more clearly.

An afterthought: I should have added the words "Stricter", "Laxer" on the two corners of the chart. This chart shows both the U.K. getting stricter but also that it joins Guyana and Netherlands as countries which treat men and women equally when it comes to drinking.
