Using a voronoi map, David Yanofsky for Quartz mapped the places in the US that are the farthest away from legal fireworks sellers in case you need to get away from the early celebrations. Or, people could just stop setting off fireworks at 1am. That would be okay too.

NASA’s Solar Dynamics Observatory has been taking a picture of the sun every 0.75 seconds for a decade. Above is a time-lapse of the resulting 20 million gigabytes of data:
This 10-year time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength that shows the Sun’s outermost atmospheric layer — the corona. Compiling one photo every hour, the movie condenses a decade of the Sun into 61 minutes. The video shows the rise and fall in activity that occurs as part of the Sun’s 11-year solar cycle and notable events, like transiting planets and eruptions.

Lauren Tierney and William Neff for The Washington Post used a rotating globe to show how connections between countries quickly shut down as the coronavirus spread.
I’m looking forward to when we get to watch the map in reverse.

Dan Kois walked all of the blocks in his ZIP Code and collected data on whether houses used serif or sans serif fonts for their house numbers:
Between March 10 and May 25, I walked every street in Arlington, Virginia’s 22207, a total distance of about 200 miles, according to my Fitbit. The ZIP code covers a lot of territory, 6.37 fairly densely populated square miles, from the Potomac River and the Washington border at the east to East Falls Church and the McLean border at the west. It includes some of Virginia’s richest and whitest neighborhoods, but also a number of apartment buildings and townhouses along Lee Highway and the historically Black middle-class neighborhood of Hall’s Hill.
Here’s the final result in a Google map. There doesn’t seem to be much of a pattern in Kois’ ZIP code, but it’s a good walking exercise. I wonder what other types of data one might collect while walking a large area.

In 1900, W.E.B. Du Bois and his students visualized black America with a series of charts. You can view the collection via the Library of Congress. One of the charts was a spiral that showed where black people lived at the time:
An FD reader asked if there was a name for the chart type, but I don’t think there’s any formal name for it. The best I could come up with was a stacked spiral chart.
It’s like a stacked bar chart that twists around. The length of the line or bar represents the data. So the longer the linear length, the greater the relative value.
Curious about making something similar in R, I made this:
The tricky part with reading this chart is that my brain seems to want to interpret area as a the visual encoding instead of line length. Arcs on the outside, while they use length, appear to take up less visual space.
I still need to experiment more, but I feel like this can be remedied with thinner lines and more space. Maybe this doesn’t work well with small multiples. I’m not sure, but the best way to find out is to put it out there and see how people interpret it.
So here’s a tutorial how to do it. Maybe it’s not the most visually efficient chart type, but these things have a way of becoming useful in the end.

Axios provides a straightforward state map showing the percentage change in the 7-day average for confirmed Covid-19 cases. Numbers are up in a lot of places.
Increased testing does not explain away these numbers. Other data points make clear that we’re seeing a worsening outbreak, not simply getting better data.
So frustrating.

Cameron Bennett made a relief map of Idaho, completely out of LEGO bricks:
In March, the COVID-induced quarantine sent me home, but more importantly, to my childhood Legos. What resulted was too much time, money, and effort spent entertaining some combination of my childhood and young adult self. By building a map. Out of Legos.
What have I even been doing with my time.

Using a wide array of sources, The New York Times shows how the virus spread at a granular level. The foundation is a map with moving dots, and the piece takes you through movements based on cell phone data and air travel in concert with known coronavirus cases.
Your jaw might drop a few times as you go through it.
Back in March, NYT published a similar work for how the spread started in China. We were talking about washing hands and restaurants closing. Thinking back to then and seeing where we are now stings.

Even though there was supposedly a person in the decision-making process and a surveillance photo wasn’t actually Robert Julian-Borchak Williams, he still ended up handcuffed in front of his own home. Kashmir Hill reporting for The New York Times:
This is what technology providers and law enforcement always emphasize when defending facial recognition: It is only supposed to be a clue in the case, not a smoking gun. Before arresting Mr. Williams, investigators might have sought other evidence that he committed the theft, such as eyewitness testimony, location data from his phone or proof that he owned the clothing that the suspect was wearing.
In this case, however, according to the Detroit police report, investigators simply included Mr. Williams’s picture in a “6-pack photo lineup” they created and showed to Ms. Johnston, Shinola’s loss-prevention contractor, and she identified him. (Ms. Johnston declined to comment.)

In crime shows, they often have this amazing tool that turns a low-resolution, pixelated image of a person’s face to a high-resolution, highly accurate picture of the perp. Face Depixelizer is a step towards that with machine learning — except it seems to assume that everyone looks the same.

Maybe you’ve seen a chart and wished you could look at the data yourself. Maybe you want to see it from a different angle. But the underlying dataset is nowhere to be found. The WebPlotDigitizer by Ankit Rohatgi lets you load an image and it will attempt to pull out the dataset. Amazing.
I can’t believe this has been around since 2010, and I’m just now hearing about it. [via @jburnmurdoch]

New York Times Opinion compared several demographics, such as unemployment and income, between majority-black and majority-white neighborhoods in the United States.
They come back to the zipper chart technique where the dots start together and then separate to emphasize the gaps. Horizontally, dots are sorted by smallest to largest difference.
