Craig Taylor from Ito World used a coral metaphor to visualize road networks in major cities around the world:

For the past six months I have been fascinated by the concept of making city networks look like living corals. The varying patterns of urban forms are inherently dictated by their road network; a complex, seemingly organic connection of links moving people across their city. Like branches of coral they have a pattern and a function, I chose to expose this pattern and manipulate it to become something far more conceptual. However, whilst being incredibly beautiful they are derived from various geo-spatial analysis of drive-times catchments making them somewhat informative as well.

Pretty.

Founded by Sue Gardner, the former head of the Wikimedia Foundation and Julia Angwin and Jeff Larson, journalists formerly for ProPublica, The Markup will aim to use data to help non-experts better understand everyday technologies that often go unchecked.

When Angwin and Larson worked together at ProPublica, their data-driven investigations included exposing discriminatory advertising practices at Facebook, bias in software that is used in criminal sentencing and algorithms that result in unfair car insurance pricing. They also uncovered evidence of domestic surveillance practices in the Snowden archives and revealed technology vulnerabilities at the President’s Mar-A-Lago country club.

“I’m excited to build a team with deep expertise that can really scale up and advance the work Jeff and I began at ProPublica,” Angwin said. “We see The Markup as a new kind of news organization, staffed with journalists who know how to investigate the uses of new technologies and make their effects understandable to non-experts.”

“People know that these new technologies are important and want to better understand their societal effects. We will help them do that,” said Larson. “The Markup will hold the powerful to account, raise the cost of bad behavior, and spur reforms.”

The venture is primarily backed by a $20 million donation from Craigslist founder Craig Newmark and $2 million from the Knight Foundation. Amazing.

Looking forward to this.

Tim Meko and Aaron Steckelberg for The Washington Post compared this summer’s rains with the average. The combination of mapping as terrain and color-encoding provides an interesting foam-looking aesthetic.

If you’re trying to learn how to work with data, make time to fiddle with the toys in your growing toolbox. Otherwise, you just have a bunch of bookmarks and no new skills.

Morph, by Datavized in collaboration with the Google News Initiative, is a tool to generate abstract images from data:

Morph exists to engage users in the creative expression of data without having to code. Generative art based algorithms turn data into a visual representation and the user can affect how their data interacts with the final visual via the algorithm. The algorithms themselves are not fixed; the user can randomly mutate, evolve and generate new algorithms creating new visuals, encouraging the sense of creative exploration and discovery.

Just upload your data, select some options to map variables to visual encodings (or have the app pick random ones for you), and see what you get. Be sure to try the “evolve” option at the end, which shows a bunch of variations of your generated image.

The results are pretty abstract, so I’m not sure if it has practical uses in the traditional data settings, but it’s fun to play with. And maybe it could be useful to quickly flip through visual encodings.

Here’s a fun piece by Andy Bergmann that shows the timeline of Earth. It’s a long-ish, straightforward scroller that vertically spaces significant events during the history of the planet. You start with the formation of Earth 4.6 billion years ago and work your way up to present day.

Hey, no one told me that baby name analysis was back in fashion. Dan Kopf for Quartz, using data from the Social Security Administration, describes the downfall of the name Heather. It exhibited the sharpest decline of all names since 1880.

Talking to Laura Wattenberg:

Wattenberg says the rise and fall of Heather is exemplary of the faddish nature of American names. “When fashion is ready for a name, even a tiny spark can make it take off,” she says. “Heather climbed gradually into popularity through the 1950s and ’60s, then took its biggest leap in 1969, a year that featured a popular Disney TV movie called Guns in the Heather. A whole generation of Heathers followed, at which point Heather became a ‘mom name’ and young parents pulled away.”

xkcd tells it like it is.

Break the visualization into its basic pieces to make it easier to make, edit, and reuse.

We talk about geographic bubbles a lot these days. Some areas are isolated, in their own bubble. Other areas seem more connected. Emily Badger and Quoctrung Bui for The Upshot looked at this geographic connectedness through the lens of Facebook friendships.

In the millions of ties on Facebook that connect relatives, co-workers, classmates and friends, Americans are far more likely to know people nearby than in distant communities that share their politics or mirror their demographics. The dominant picture in data analyzed by economists at Facebook, Harvard, Princeton and New York University is not that like-minded places are linked; rather, people in counties close to one another are.

There are two main parts to the piece. The first one is a county map that you can mouse over to see the likelihood of friendship with those in other counties. The second part imagines a country split up into regions based on Facebook connections. Be sure to catch them both.

Hurricane Florence brought a lot of rain, which in turn made river levels rise. The New York Times animated the rise over a five-day period. The height of the bars represents the rise of the river level, as compared to levels on Thursday.

I like the visual metaphor of bars going up with river levels. I’m not sure the sudden rise and falls in such short periods of time would appear as surprising.

When you try to describe the size of something but don’t have an exact measurement, you probably compare it to an everyday object that others can relate to. Using the Google Books Ngram dataset, Colin Morris looked for how such comparisons changed over the past few centuries.

I especially like the bits of history to explain why some words fell into and out of fashion.

There are endangered species where the remaining few in the world could fit on a single car train. Mona Chalabi for The Guardian imagined such a scenario.

Usually when we talk about scale and putting numbers into perspective, it’s about imagining the large ones. What does a million look like? A billion? Chalabi’s illustrations take it the other direction.

Typhoon Mangkhut went through the northern end of the Phillipines a few days ago. At least 25 people died. The New York Times provides a scrolling 3-dimensional view using data collected by NASA satellites.

I talked with Moritz and Enrico on Data Stories, my favorite visualization podcast. They’ve been providing a healthy balance of practice and research since 2012.

I don’t dare listen to myself, but based on the show notes we talked about FlowingData over the years, some of the changes in visualization, and answered listener questions. You can listen here.
