Mapping Nuclear Reactors

Today’s piece is a map from the Economist. It looks at the state of nuclear energy across the world. Slovakia caught my eye because when I recently traveled across that country I glimpsed from my train the massive complex near (I think) Trnava. Apparently those are also some of the youngest reactors out there.

Mapping Hepatitis vs HIV

I don’t often write about maps, especially of the choropleth kind. In many cases I choose not to because so many of the maps are one-dimensional: how fast is x growing across the world; which is predominant across the world, y or z? So I was pleasantly surprised by the Economist yesterday when they published this interactive map on the scourges of hepatitis and HIV.

Quickly put, the map is a success. It shows a clear geographic pattern; the developed/Western world along with the Middle East and Asia have a larger problem in hepatitis than HIV whereas Africa and Latin America are dealing moreso with HIV. (Admittedly, the fact that 117 out of 187 countries are dealing more with hepatitis is lost because so many of the countries are small in area.) But, the really nice bit about the map is not just the colour by virus, but the tint by comparative ratio. The darker the colour, the stronger the one virus over the other.

Lastly, from a data perspective, I just wonder if the ratios could not be adjusted for population, or deaths as a percentage of the national population? I would be curious to see if that would yield interesting results.

Queue for the British Throne

So apparently a baby was born in London…as was another who is likely to become the future King of the Great Britain and Northern Ireland (not of England). But the British love their queues and so this infant will have to wait in line just like everyone else (in the royal line of succession). The Economist visualised just how long these waits have been for English and British monarch vis-a-vis their time spent on the throne.

More Effective Cartograms

The other day I posted an example of a good cartogram, actually a pair of good ones from the New York Times. Today, I wanted to share another good example. The Economist created this cartogram, map of Great Britain’s constituencies. What is perhaps most effective in this chart, even more so than in the Times’, is its use of a “traditional” map form for comparison. You quickly get a sense of how large rural Britain’s constituencies are compared to those of London.

National Pi Day

Yesterday was National Pi Day. That’s Pi as in 3.14…not as in pie pie. Unless you celebrated Pi Day with pie. In which case, way to go, you. Me, I’m more traditional. I celebrated Pi Day with talk of pie charts. But at the Wonkblog over at the Washington Post, Sarah Kliff posted about several really impressive pie charts.

My favourite was the actual advertising done by the Economist back in Philly a few years ago. Their advert was printed atop a pizza pie box. It’s the double-whammy of Pi Day: pie charts atop a pizza pie.

The image below comes from a different site about the Economist ad campaign, found here, but the link goes to the celebration of pi with pie.

The Realms of GAFA

The Economist often does clear, concise graphics to accompany their articles. And from to time they also do more interactive works  that allow a more in-depth exploration of data. And then sometimes they do awesome maps like this. The realms of GAFA.

Mexico: the Land of Many Countries (or Comparisons Thereto)

On Thanksgiving, the Economist published an interactive map that looked at Mexico across three metrics: murders, murder rates, and population. Mexico is one of the more populated countries in the world, but it is also one of the most dangerous. In the middle of the previous decade, the Mexican government began to crack down on the drug cartels. But the cartels have violently resisted. Very violently.

The map is nothing new. It labels different Mexican states by comparing their statistics to those of countries across the world. For example, the state of Chihuahua in northern Mexico, one of the “fronts” of this new drug war, has a population of 3.41 million people. The total number of murders so far this year is 2,350. That is only six murders fewer than in the entire country of the Ukraine. Did I mention the population of the Ukraine is over 45 million. More than ten times the size of Chihuahua. And the comparisons go on, though as the map clearly points out the distribution is not uniform.

In terms of interactivity, a nice little feature is the filtering of the map by the legend at the bottom. Hover over one of the bars and only those areas appear coloured in the map.

I Just Want to Retire

I don’t know about you, but I’ve got goals in life. Namely to retire. So thankfully the Economist put together this infographic on retirement age across the OECD (a cool club of rich countries), specifically to look at how retirement ages have changed between 1970 and 2010 alongside life expectancy.

363 Days

We are now just under 365 days away from Election Day 2012. Without a doubt, I shall have many politically-themed graphics coming. People just have to start making them. But for now, the Economist kicked it off Monday—when it was 365 days—with a motion graphic piece that outlines some of the polling numbers and challenges to the Republicans vying for power and President Obama determined to keep it.

Certain types of the chart are very much not helpful in determining the actual numerical comparisons. But, with the voiceover keeping our attention and explaining what is going on with the charts, it is as always interesting to experience a story told in charts and graphs for nearly three minutes. And about a story with real significance.

What’s In a Tweet?

Tweeting in 140 characters would seem to give one little information, aside from interesting ways of shortening and truncating the English language. However, if you dig just a little deeper than the blurb of text, one can find a whole lot more information that companies—surprise—find valuable.

This graphic, originally by Raffi Krikorian at Twitter, is via the Economist as part of the Daily Chart blog. Certainly the topic is interesting and the diagram useful, but it could probably a bit more structure and clarity in terms of arranging the information. But, if one takes the time to read through it, the breakdown of a single Tweet is quite fascinating.
