Today’s post relates very much to yesterday’s post. But this one is from the New York Times and uses aerial photography to showcase how the Jefferson grid system works in reality after it was implemented as shown yesterday.

A few weeks back I looked at my ancestral family’s land grant in Wisconsin. Unlike land on the East Coast that was surveyed and organised by pioneers in different colonies using different sets of rules, after the formation of the United States, surveyed land was organised into townships that had subdivisions. In this blog post I found about the subject, there are several diagrams and maps that explain just how this system worked.
How western lands were organised
If you’re curious about how western land was organised, its worth a quick read.

I have returned from my trip up north to Minnesota and Wisconsin. Unfortunately, from the research side it was not the most successful of trips. I did find some records, but none that answered any of the big questions I had. If anything, I now have far more questions. Most of the information I learned deals with the homesteaded land that John Spellecy received in 1888, at the young age of 70. It turns out by the time he was given the land by the US government, he had already made one contract to sell a portion of it. And so to make some semblance of it, I made this animation to show how the land grant disappeared over only a 12 year period.
How the Spellecy plot disappeared
For the curious, the background image is a digitisation of the US government’s original land survey. The A.160 denotes 160 acres, the maximum allowed by a homestead claim.
Today the Supreme Court takes up gay marriage. Again. This is, you know, after they decided two years ago that the federal government has to recognise gay marriages when performed in states where it is legal. Anyway, last week, Bloomberg Business looked at the United States preference for changing its mind through a nice series of charts.
How interracial marriage changed in the US
They took six key issues, including interracial marriage shown above, and looked at how the position shifted over time. They identified the basic trend as being early adopter states followed by rapid acceptance to a critical mass, at which time the federal government stepped in, e.g. via the Supreme Court.

For those of you who don’t know, the British Parliament was dissolved today ahead of the 7 May elections. In other words, it is now election time. Last week the Economist published a small interactive piece that allows you to look at the composition of the British Parliament from 1870 through today.
Parliament over the years
While many (some?) of us would remember times from recent history, e.g. the 1997 electoral victory of Tony Blair, the memory might be a bit foggier one hundred years in the past. But to help you, if you click on a particular year, the view changes from an overview to a focus on Parliament in that particular year.

Lee Kuan Yew died this weekend. He is lately responsible for designing and implementing the policies that transformed Singapore from a poor fishing village to a commercial hub. The transformation came at a price of course. Singapore enjoys limited free speech and the country is effectively a one-party state, with the one party now controlled by Lee Kuan Yew’s son. Regardless of the faults, the transformation itself is remarkable. And the Economist put together a timeline to showcase that.

I always enjoy the combination of two of my interests: data visualisation and genealogy. So this BBC article that references a Nature article piqued my interest. It looks at the distribution of DNA across the United Kingdom and identifies different cluster areas. The most important finding is that the Celts, i.e. the people of Scotland, Northern Ireland, Wales, and Cornwall are not a single genetic group. Another finding of interest to me is that the people of Devon are distinct from both Cornwall and Dorset, Devon’s bordering regions. That interest is because my New England ancestors largely hailed from Devon and Dorset.

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.
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.
