Christmas countdown

The Daily chart Advent calendar

Dec 23rd 2011, 15:59 by The Economist online

A round-up of the year's most popular graphics and charts

WELCOME to our Daily chart Advent calendar, a collection of the 24 most popular maps, charts, data visualisations and interactive features published on our site 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. Season's greetings from us all at The Economist online.

UPDATE - December 24th: And the winner is... Stateside substitutes.

Behind door 24, the most popular infographic of 2011 is revealed as our interactive "US equivalents" map, which compares American states with entire countries on a number of measures. You'll also find links to the other "country comparisons" in our range, which also proved immensely popular this year.

And be sure to visit again on Christmas day to discover our bonus graphic behind the final door.
