The tree rings of US immigration

Here’s an unusual way of representing population growth. Pedro M Cruz, from Northeastern University in Boston, takes two centuries of US census data and shows the increasing population as rings of a tree, one for each decade.

For a radical new perspective on immigration, picture the US as an ancient tree
According to Cruz, the tree metaphor ‘carries the idea that these marks in the past are immutable’ and it ‘embodies the concept that all cells contributed to the organism’s growth’. As with so many renderings of US history, indigenous populations are conspicuously absent from the tableau. Still, Cruz’s skilfully deployed data doubles as a resonant work of cultural commentary, offering a rich and often surprising look at the ever-evolving makeup of the country.

There’s more information on the video’s Vimeo page.

Simulated dendrochronology of U.S. immigration (1830-2015)
Trees in their natural setting have annual growth rings that reflect varying environmental conditions; the rings’ forms are neither perfect circles nor ellipses. The algorithm is inspired by this variation and accordingly deposits immigrant cells in specific directions depending on the geographic origin of the immigrant. Rings that are more skewed toward the country’s East, for example, show more immigration from Europe, while rings skewed South show more immigration from Latin America. With this, it is possible to observe the quantity of immigration through the thickness of the rings. The color of the cells corresponds to specific cultural-geographical regions.

Charting frustration

An interview with US artist, Christine Sun Kim.

An artist who channels her anger into pie charts
A series of her large-format charcoal drawings, which explore navigating the hearing world as a deaf person, are now on view at the 79th Whitney Biennial in New York. The six works pair depictions of varying mathematical angles with correlative, rage-inducing encounters that are both broadly applicable — “being given a Braille menu at a restaurant” or “offered a wheelchair at an airport” — and painfully specific to her experience — “curators who think it’s fair to split my fee with interpreters.”

Channeling her experiences into images of geometric angles, musical notes and meme-like pie charts, Kim playfully combines different sign systems to create what she calls a “common language that all people can connect to.”

The crowded race to the top

Nominations officially open today for Theresa May’s replacement. The sprint is expected to reach the finish line towards the end of next month, and the press are frothing all over it.

But consider this look at the US presidential marathon race, with a year and a half still to go.

More candidates and earlier
We’re 536 days out and 23 Democrats are in. In contrast, there were 8 around this time in 2008.

Ta ra, Theresa

The press are keen to analyse her political legacy (blah blah blah blah), but I’d rather look at Prime Minister May’s time at Number 1O via two of my favourite things – photos and charts.

The political life of Theresa May – in pictures
A look back over May’s political career, from being elected as MP for Maidenhead in 1997 to Brexit, the snap election that backfired and her onstage dancing at the 2018 Tory conference.

Remember buying music?

Here’s a simple but very effective chart showing the rise and fall of various music formats. This brings back memories.

Visualizing 40 years of music industry sales
For people of a certain age group, early memories of acquiring new music are inexorably linked to piracy. Going to the store and purchasing a $20 disc wasn’t even a part of the thought process. Napster, the first widely used P2P service, figuratively skipped the needle off the record and ended years of impressive profitability in the recording industry.

Napster was shut down in 2002, but the genie was already out of the bottle. Piracy’s effect on the industry was immediate and stark. Music industry sales, which had been experiencing impressive year-over-year growth, began a decline that would continue for 15 years.

A typical day, comically speaking

Via FlowingData, here’s a witty visualisation of how we spend our days, on average. It’s just a stacked bar chart, but turning it into a comic “can allow the audience to identify with the story, sparking self-reflection: “Is this how I live my life? How am I different?””

A day in the life of Americans: a data comic
There are three settings in this comic (a bedroom, an office, and a bar), each serving as a metonym for an activity (sleep, work, and leisure). I have also included colors and positions as redundant, but clarifying, codes of classification. Such scenes allow for a novel method of highlighting data; a setting inside a panel is “lit up” by a light source if the activity for which it stands occupied those two hours of Americans the most.

Process unclear

Another day, another flowchart trying to explain the remaining Brexit options, at the end of this article from the BBC on Jeremy Hunt’s take on recent events.

Brexit: Jeremy Hunt says ‘absolute priority’ to avoid European polls
The foreign secretary said the public would find it “hugely disappointing” to be asked to send MEPs to Brussels. Asked if it could be a disaster for the Tories, he told the BBC “in terms of polling it certainly looks that way”.

Brexit: What happens now?
The UK was originally due to leave on 29 March. The first extension shifted that date to 12 April. But now the UK now has just over six months to decide what it wants to do.

Government ministers are continuing talks with Labour leaders to try to find a compromise deal. If they can agree, MPs will be given a chance to vote on the deal. If not, a range of alternative options will be put to them instead.

Self-improvement

The Economist’s charts are usually very clear and helpful, but that’s not to say they can’t be improved – as they themselves show.

Mistakes, we’ve drawn a few
At The Economist, we take data visualisation seriously. Every week we publish around 40 charts across print, the website and our apps. With every single one, we try our best to visualise the numbers accurately and in a way that best supports the story. But sometimes we get it wrong. We can do better in future if we learn from our mistakes — and other people may be able to learn from them, too. […]

Misleading charts
Let’s start with the worst of crimes in data visualisation: presenting data in a misleading way. We never do this on purpose! But it does happen every now and then. Let’s look at the three examples from our archive.

Explaining the Brexit endgame

Another Brexit vote, another significant defeat. Here are a couple of useful charts outlining what might happen next.

It’s enough to drive you mad.

Brexit has become a mental health issue
Hamira Riaz, a clinical psychologist based in the UK, says it’s not surprising that the uncertainty over Brexit is weighing on mental health. If “you suddenly find that decisions that are made on a national level are impacting your material security, that is definitely going to be a significant negative life event,” she explains. “And we know that people facing significant negative life events can tip over into mental health issues—such as depression and anxiety.”

[…]

The UK’s National Health Service could find itself less able to address mental health issues in the near future. An NHS briefing (pdf) last year said Brexit’s impact on mental health services would be “far reaching,” in part because of the risks it poses to the supply of workers. About 165,000 NHS employees are EU nationals, and while those that are already in the UK can apply to stay, domestic recruitment alone won’t be able to meet future staffing needs.

And how about this for a summary of the key issues here?

Size matters

How long is the perfect book?
British novelist E.M. Forster once complained that long books “are usually overpraised” because “the reader wishes to convince others and himself that he has not wasted his time.” To test his theory we collected reader ratings for 737 books tagged as “classic literature” on Goodreads.com, a review aggregator with 80m members. The bias towards chunky tomes was substantial. Slim volumes of 100 to 200 pages scored only 3.87 out of 5, whereas those over 1,000 pages scored 4.19. Longer is better, say the readers.

The phenomenon that Forster describes, akin to literary “Stockholm syndrome”, is only one possible explanation, as the article goes on to explain.

books-future-perfect-1

I like that phrase, ‘literary Stockholm syndrome’. I wonder, though, if the age of the reader is relevant — I certainly feel less patient with these longer books as I grow older. (And less patient generally, if my family is to be believed!)

Weeks, years, aeons

I have a birthday coming up in a few days and I was going back over this post that links to a Wait But Why article on how to see all the weeks in your life in one go.

Your life in weeks
Sometimes life seems really short, and other times it seems impossibly long. But this chart helps to emphasize that it’s most certainly finite. Those are your weeks and they’re all you’ve got.

I’ve found it very useful to go back to my own version of this, to remind myself of where I’ve been and how fleeting situations are sometimes. But I hadn’t realised there was another article there that gives you a much broader — but still very relatable — perspective on time.

Putting time in perspective
Humans are good at a lot of things, but putting time in perspective is not one of them. It’s not our fault—the spans of time in human history, and even more so in natural history, are so vast compared to the span of our life and recent history that it’s almost impossible to get a handle on it. …

To try to grasp some perspective, I mapped out the history of time as a series of growing timelines—each timeline contains all the previous timelines.

You move quickly through the last day, week and year, through timelines of a 30 year old and a 90 year old, all the way back to when humans diverged from apes, and the ages of the Earth and Sun.

History is much closer than you think.

Drawing data

With perhaps the funniest headline I’ve seen in a while, the ever-reliable It’s Nice That website has this interview with the remarkable Mona Chalabi, as part of its International Women’s Day series:

“If it’s about farts, draw a butt for god’s sakes”: Mona Chalabi tells us how to illustrate data
By day, Mona is a data editor at the US version of the Guardian where she uses self-taught illustration methods to bring data to life. Covering everything from body hair removal to the popularity of nose jobs in the US to the number of decapitated animals found in New York parks, Mona’s tongue-in-cheek approach to information communication has won her column inches and an immovable place in our hearts.

There are many more of her illustrations on her website, as well as links to her journalism and videos.

All the graphs you can eat

What’s better than data and loads of graphs? Data and loads of graphs about food and drink, of course!

Britain’s diet in data
The British diet has undergone a transformation in the last half-century. Traditional staples such as eggs, potatoes and butter have gradually given way to more exotic or convenient foods such as aubergines, olive oil and stir-fry packs. Explore the changes across four decades and hundreds of food and drink categories in this interactive visualisation, featuring data from the Department for Environment, Food and Rural Affairs (Defra).

Whilst I’m not surprised to see the fall of lard and the rise of olive oil over the last 40 years, why is nobody buying marmalade anymore? Goodness me.

Visualising data; the good, the bad and the quirky

The data’s everywhere, but can we make sense of it? Here are some data visualisation approaches and examples – how to do it, and how definitely not to.

This article suggests the young folks are demanding better presentations of statistical data because of Google or Wikipedia or something. Sounds fishy. Surely us old folks appreciate good design too?

Data visualization drives the era of information activism
Having grown up with the web, millennials are used to having access to all the information they want with just a simple finger tap on a screen. As millennials enter the workforce, they are bringing these expectations into the office, behaving less as data consumers and much more as information activists.

But how far should we go in leading the horses to the water?

Narration and exploration in visualization
What should we emphasize when designing a visualization? Should we explain the data, perhaps through a narration, or should we let readers explore the data at will?

Here’s an example of how an interactive presentation not only helps with a story but can spur you into looking for your own.

What happens when a newspaper editor and a data-viz whiz team up to tell stories
With two wins behind them, Rob and Daniel are already discussing future collaborations—perhaps something with sports or crime data. The idea is to tell compelling data stories that have a longer shelf life. (“If you put time into creating something like this, you want people to see it over a certain scale of time,” says Daniel.)

I do like these images, though. Not sure how replicable this approach is, but it works well here.

These playful, funny 3D printed infographics can liven up any data
Instead of flicking hastily to the next page, your gaze can’t help but linger on the adventures of the miniature figures scaling, swinging from or exploring the plastic pieces.

But here are the real gems. Bar pies? Caramel latte football fields?

BestWorstViz contest result
As with last month’s graphiti contest, picking a winner was ever so hard with lots of wonderfully bad work heading my way. The submissions generally fell into two different camps: (1) the most blatant, inelegant in-your-face explosions of design awfulness, and (2) the more subtly deceptive “wolf in sheep’s clothing” designs. My judgments were based on the degree of violation against each of my three key principles: Trustworthy, accessible and elegant.

But who could possibly hate Excel?

This tool makes it stupid simple to turn data into charts
Here’s something handy for people who hate Excel. Venngage, the company that lets you make infographics with the click of (a few) buttons, recently launched a new product called Beam. Beam does for charts what Venngage does for infographics as a whole. Which is to say, it makes the process of transforming data into useful visuals very, very easy.

And they look really spidery too

Another great Excel article from Mynda Treacy​, this time about her​​ views on radar charts. It’s safe to say she’s not a fan. Some great points here about data visualisation and how to get messages across. I’ve never used a radar chart, but that’s more because I’ve never really understood them.

Excel alternatives to radar charts
Radar charts display data in a circular fashion, which is the opposite of the straight line comparisons we’re able to subconsciously perform. This means we have to work hard to make any comparisons and as a result we’re likely to make mistakes in our assumptions.​

She mentions this article ​by Stephen Few, who weighs in further but does recognise when these radar charts might have their uses.

Keep radar graphs below the radar – far below (pdf)
This one advantage motivates me to ease up just a bit on my repugnance toward radar graphs.

Excel Box and Whisker Diagrams

Excel box and whisker diagrams (box plots)
Box and Whisker Charts (Box Plots) are commonly used in the display of statistical analyses. Microsoft Excel does not have a built in Box and Whisker chart type, but you can create your own custom Box and Whisker charts, using stacked bar or column charts and error bars. This tutorial shows how to make box plots, in vertical or horizontal orientations, in all modern versions of Excel.
