A holiday gift for data and reference geeks!
From the The Economist 2014 Advent Calendar Web Page:
[The calendar features] a collection of the 24 most popular maps, charts, data visualisations and interactive features published on our site [Economist.com] this year. You’ll find one behind each door, with a new door available to open every day until Christmas, plus an entirely new chart behind door number 25—a Christmas gift from the Daily chart team.
