Tree Maps

Spring is the time for the blossoming of cherry trees. Philadelphia has its own cherry blossom festival, but Washington’s is even bigger. The Washington Post put together a small infographic about the the trees, the symbolism, and the reason behind the presence of Japanese trees in the capital of the United States.

But, mostly I get to say we have a good example of a tree map.

The Disappearing Polish S

Today’s piece is not a chart, nor is it some complicated piece of data visualisation. Instead, we are looking at a piece from Medium that attempts to explain the disappearing Polish S. Basically, it is a roundabout way of saying that it is very difficult to type in foreign languages on American keyboards because of the additional letters and/or diacritics. If you are at all interested in typography, the article makes nice use of comparative photographs and highlighted colours in the alphabet to illustrate its case.

A Year on Pluto

Last week, NASA’s Dawn probe entered orbit above Ceres, a dwarf planet in the asteroid belt. But later this summer, the New Horizons spacecraft is set to race past Pluto, formerly a planet but now a dwarf planet. New Horizons launched in 2006 and will have taken nine years to reach Pluto. But how long is a year on Pluto? Thanks to the New Horizons team, we can see how one year on Pluto is 248 Earth years, or longer than the history of the independent United States.

Understanding Genealogy

I came upon this piece a little while ago and realised that it in some ways paralleled my own interest in genealogy. Basically the story comes down to realising that you probably only know a mere fraction of the stories behind all the people who led up to you. To put in another context: “you’re the product of 127 romances, just in the last 200 years alone”. Anyway, the article is a nice read and explains the math with illustrations.

Wars Are Bad, But Not as Bad as They Used To Be

War is bad for the population business—arguably good for business business. A year ago, the Hague Centre for Strategic Studies released a .pdf that looked at peace and conflict and their respective drivers. The designers clumsily pieced everything together so that the sum is less than the constituent parts. But, if you isolate each piece and look at it alone, you can ignore the overall design and focus on the merits of each component. The excerpt below looks at the deaths in wars over time and their share of world population.

Lynchings

Let’s follow up yesterday’s good news story about measles with lynchings. The New York Times mapped and charted historical lynchings from 1877 to 1950 across 12 states in the South.

Masses and Payloads

While last week ended with an xkcd post, I want to start this week with an older one I missed about spacecraft. Because spacecraft are awesome every day of the week. In particular it looks at mass and payload capacity of spacecraft and rockets over time.

The American Empire

The United States has a long history of deploying troops overseas. How long? And where to? Well, ABC (as in the Australian Broadcasting Corporation) mapped out every US deployment dating back to 1798. I captured the year 2014, but if you are curious, you should check it out for yourself.

A neat little bonus, watch the growth of the borders of the United States from 1798.

Armistice Day

Today is Armistice Day, alternately known as Remembrance Day or Veterans Day. Originally the date remembered the armistice that ended World War I (hence those two names). The war ended at the 11th hour on the 11th day of the 11th month. But in the preceding years, millions of Europeans died along with just over a hundred thousand Americans. (We entered the war quite late.) This had a dramatic impact on the populations of European countries. In the United Kingdom, the Office of National Statistics put together a page for Remembrance Day 2014 that looks at four charts detailing the changes to the UK’s population structure. Suffice it to say there were lasting effects.

The Fall of the Berlin Wall

Yesterday marked the 25th anniversary of the fall of the Berlin Wall. But with the reunification of Germany a year later, has the former East Germany been able to catch up to what was West Germany? The Economist looks at the results in this graphic and the answer is yes. And no.
