Baby, It’s Hot Outside

Those of you living on the East Coast, specifically the Mid-Atlantic, know that presently the weather is quite warm outside. As in levels of dangerous heat and humidity. Personally, your author has not left his flat in a few days now because it is so bad.

Alas, not everyone has access to air conditioning in his or her abode. Consequently, they need to look to public spaces with air conditioning. Usually that means libraries or public buildings. But here in Philadelphia, have people considered the subway?

Billy Penn investigated the temperatures in Philadelphia’s subsurface stations along the Broad Street and Market–Frankford Lines—Philadelphia’s third and oft-forgot line, the Patco, was untested. What they found is that temperatures in the stations were significantly below the temperatures above ground. The Market–Frankford stations, for example, were less than 100ºF.

Just explore the rails…
Just explore the rails…

Of course that misses the 2nd Street station in Old City, but otherwise picks up all the Market–Frankford stations situated underground.

Then there is the Broad Street Line.

More rail riding…
More rail riding…

Here, I do have a question about why the line wasn’t investigated from north to south. It ran only as far north as Girard, stopping well short of north Philadelphia neighbourhoods, and then as far south as Snyder, missing both Oregon and Pattison (sorry, corporately branded AT&T) stations. The robustness of the dataset is a bit worrying.

The colours here too mean nothing. Instead blue is used for the blue-coloured Market–Frankford line and orange for the orange-coloured Broad Street line. (The Patco line would have been red.) Here was a missed opportunity to encode temperature data along the route.

Finally, if the sidewalk temperatures were measured at each station, I would want to see that data alongside and perhaps run some comparisons.

This is an interesting story, but some more exploration and visualisation of the data could have taken it to the next level.

British English vs. Irish English

The United Kingdom is known for having a large number of accents in a—compared to the United States—relatively small space. But then you add in Ireland and you have an entirely new level of linguistic diversity. Josh Katz, who several years ago made waves for his work on the differences in the States, completed some work for the New York Times on those differences between the UK and Ireland.

You might know this as tag. At least I do.

Why do I bring it up? Well, your author is going on holiday again, this time back to London. I will be maybe taking some day trips to places outside the capital and maybe I will confirm some of these findings. But if you want, you can take the quiz and see where you fall compared to Katz’s findings.

And it does pretty well. It identified me as being clearly not from the British Isles.

Maybe I'm secretly Cornish?

But depending upon how you answer a particular question, the article will show you how your answer compares.  Let’s take my answer for scone. In that, I am more Irish.

Or you can just call them fantastic and delicious.

The Great Migration Map

Yesterday in a post about Angela’s forced journey from Africa to Jamestown I mentioned that the Pilgrims arrived at Plymouth Bay just one year later in 1620. From 1620 until 1640 approximately 20,000 people left England and other centres like Leiden in the Netherlands for New England. Unlike places like Jamestown that were founded primarily for economic reasons, New England was settled for religious reasons. Consequently, whereas colonies in Virginia drew young men looking to make it rich—along with slaves to help them—New England saw entire families moving and transplanting parts of towns and England into Massachusetts, Rhode Island, Connecticut, and New Hampshire.

New England kept fantastic records and we know thousands of people. But we do not know whence everyone arrived, but we do know a few thousand. And this mapping project from American Ancestors attempts to capture that information at the English parish level. At its broadest level it is a county-level choropleth that shows, for those for whom we have the information, the majority of the migration, called the Great Migration, came from eastern England, with a few from the southwest.

Quite a few from Norfolk, Suffolk, and Essex

You can also search for specific people, in which case it brings into focus the county and the parishes within that have more detail. In this case I searched for my ancestor Matthew Allyn, who was one of the founders of Hartford, Connecticut. He came from Braunton in Devon and consequently appears as one of the two people connected to that parish.

Devon did not have nearly as many people emigrate as the eastern counties

But was Thomas related to Matthew? We don't know.

Overall, it’s a nice way of combining data visualisation and my interest/hobby of genealogy. The map uses the historical boundaries of parishes prior to 1851, which is important given how boundaries are likely to change over the centuries.

This will be a nice tool for those interested in genealogy and that have ancestors that can be traced back to England. I might be biased, but I really like it.

An Illustrated Guide to the Deaths in Game of Thrones

Did something important happen yesterday in the news? We’ll get to it. But for now, it’s Friday. You’ve made it to the weekend. So sit back and binge. On gin or Game of Thrones, whatever.

Last Sunday the hit HBO show Game of Thrones returned for its final series. I did not have time to post about this piece then, but thankfully, not much has changed.

It details all the on-screen deaths in the show. (Spoiler: a lot.) It includes the series in which they died, the manner of their death, who killed them, and some other notable information. Remarkably, it is not limited to the big characters, e.g. Ned Stark. (If that is a spoiler to you, sorry, not sorry.) The piece captures the deaths of secondary and tertiary characters along with background extras. The research into this piece is impressive.

Don’t worry, if you haven’t seen the show, this spoils only some extras and I guess the locations the show has, well, shown.

Don't go beyond the Wall
Don’t go beyond the Wall

Thankfully, by my not so rigourous counting, last week added only four to the totals on the page (to be updated midway and after the finale).

In terms of data visualisation, it’s pretty straightforward. Each major and minor character has an illustration to accompany them—impressive in its own right. And then extras, e.g. soldiers, are counted as an illustration and circles to represent multiples.

For me, the impressive part is the research. There is something like over 60 hours of footage. And you have to stop whenever there is a battle or a a feast gone awry and count all the deaths, their manners, identify the characters, &c.

The Fire at Notre Dame Cathedral: Part Trois

On Tuesday I talked about a small article published by the New York Times that looked at the cathedral fire. I lamented that there were no immediate graphics explaining what happened. Just give me two days. Tuesday we had the BBC piece and then yesterday the New York Times published a more extensive look.

As the user scrolls through the piece, a 3-dimensional model reveals the key structural elements whilst text explains why that part is being focused upon in the story.

Wood beams do not make for preventative measures.

I do not know if the dramatic, black background helps. It might create contrast the designers deemed helpful against the light-coloured illustration. But that is probably my only real point to make about the piece. Otherwise, it is a very thorough and helpful guide to the architecture and how that helped the fire spread.

Public Transit of Yesteryear

For my frequent readers, it will be no big surprise that I am avid supporter of public transit, especially the railways. Consequently I was delighted when I read a non-Brexit piece in the Guardian yesterday that looked at public transit systems in several cities.

But it did so by comparing earlier plans or systems to those in existence today.

That's definitely one time I'd like to live in the past.

Each design is slightly different and reflects the source material for the various cities. But I naturally selected the Philadelphia map. One of the biggest things to notice are the lack of trams/trolleys north of Girard and the addition of the River Line.

Angry Birds? Bad Birds

Baseball is almost upon us. And oh boy do the Baltimore Orioles look bad. How bad? Historically bad. FiveThirtyEight went so far as to chart the expected WAR, wins above replacement, of each position of all teams since 1973. And the expected Orioles lineup looks remarkably bad.

They are going to be so bad.
They are going to be so bad.

What is nice about this graphic is the use of the medium grey for each team/year combination. I may have used a filled orange dot instead of open, but the dots do at least standout and show the poor positioning of just about everything but the second baseman.

The Long and Winding Road

This Washington Post piece caught my eye earlier this week. It takes a look back at all the departures from the Trump administration, which has been beset by one of the highest turnover rates of all time.

So many names.
So many names.

What I like about the piece is how it classifies personnel by whether or not they require Senate confirmation. For example, Ryan Zinke as Interior Secretary had to be approved by the Senate. Nick Ayers, Pence’s former chief of staff, did not.

Importantly each name serves as a link to the story about the person’s departure. It serves as a nice way of leading the user to additional content while keeping them inside the graphic.

The further down the piece you go, there are notable sections where blocks of body copy appear in the centre of the page. These provide much more context to the comings and goings around that part of the timeline.

Are Baseball’s Big Contracts Worth It?

On Tuesday the San Diego Padres signed Manny Machado to a guaranteed contract worth $300 million over the next ten years—though he can opt out after five years. Machado was one of two big free agents on the market, the other being Bryce Harper. One question out there is whether or not these big contracts will be worth it for the signing teams. This piece yesterday from the New York Times tries to look at those contracts and how the players performed during them.

Oh, David Price…
Oh, David Price…

Like the piece we looked at Tuesday, this takes a narrative approach instead of a data exploratory approach—the screenshot above is halfway through the read. Unlike the Post piece, this one does not allow users to explore the data. Unlabelled dots do not reveal the player and there is no way to know who they are.

Overall it is a very strong piece that shows how large and long contracts are risky for baseball teams. The next big question is where, for how long, and how much will Bryce Harper sign?

Be Like Mike?

Back in 2012 the New York Times ran what is a classic data visualisation piece on Mariano Rivera. It tracked the number of saves the legendary Yankees closer had over his career and showed just how ridiculous that number was—and how quickly he had attained it. Last week, the Washington Post ran a piece that did something very similar about LeBron James, a future basketball legend, and Michael Jordan, definitely a basketball legend.

They might have game.
They might have game.

The key part of the piece is the line chart tracking points scored, screenshot above. It takes the same approach as the Rivera piece, but instead tracks scored points. Unlike the Rivera piece, which was more “dashboard” like in its appearance and function, allowing users to explore a dataset, this is more narratively constructed. The user scrolls through and reads the story the authors want you to read. Thankfully, for those who might be more interested in exploring the dataset, the interactivity remains intact as the user scrolls down the article.

While the main thrust of the piece is the line chart, it does offer a few other bar and line charts to put James’ career into perspective relative to the changing nature of NBA games. The line chart breaking down the composition of James’ scoring on a yearly basis is particularly fascinating.

But, don’t ask me about how he fits into the history of basketball or how he truly compares to Michael Jordan. Basketball isn’t my sport. But this is a great piece overall.
