Martin Wattenberg and Fernanda Viegas from Google Research ran with the book metaphor for visualization in their talk at Tapestry 2014. Unlike some who bash projects that don’t fit a narrow specification, Wattenberg and Viegas argue that visualization spans various genres. The key is to know your genre and create accordingly.

Gift-buying season is in full swing, and it’s time to get stuff for your loved ones. But, it has to be tangible, because stuff that occupies space in the physical world is how you tell someone you love him or her by that amount. I know this, because the UPS truck that delivers to my neighborhood had an additional trailer rigged to the back full of it.

Here are some data-ish printed things to show your loved ones that you care. We’re approaching last-minute territory for packages that don’t arrive with an Amazon smiley on the side.

In 1971, Nobel laureate economist Thomas Schelling proposed that a desire to have neighbors of the same race — even a small percentage — can lead to segregation. The model has been simulated through a variety of interactives before, but in Parable of the Polygons, Vi Hart and Nicky Case put extra effort into teaching the model, bringing playfulness to an otherwise serious subject.

Two groups of people are encoded as shapes — squares and triangles — and they take you through each step of the model. Use the sliders to adjust thresholds and population distributions, and run the simulation. The shapes on the left move if they’re looking for similarity, and the line chart on the right shows segregation over time.

You end up with an understanding of how segregation works (however simplified this model might be) and a glimmer of hope of how we might shift directions.

Worth a try.

Sports loves conditional distributions. What does Joe Billy Bob typically do against such and such team? How does play differ in wins and losses? And a lot of the data is easily accessible, which makes it straightforward to answer these questions. Buckets, by Peter Beshai, uses NBA data to explore shot selection with plenty of conditionals.

TNT described NBA player Anthony Davis’ growth and accompanied the discussion with a graphic that showed a picture of Davis over the years. To drive the point home I guess they made the image of Davis bigger each step. SB Nation had some fun with predictions of Davis’ future. The NBA is going to have a heck of time adjusting the rules for Godzilla.

Sweet, I guess Fox News had it right all along. I’m going to save a ton of space by truncating my vertical axes from now on. I just might go back and retrofit all of my old charts too. [via Reddit]

Eric Fischer, known around these parts for his detailed dot maps, describes his process along with a code release.

I’ve been tracking geotagged tweets from Twitter’s public API for the last three and a half years. There are about 10 million public geotagged tweets every day, which is about 120 per second, up from about 3 million a day when I first started watching. The accumulated history adds up to nearly three terabytes of compressed JSON and is growing by four gigabytes a day. And here is what those 6,341,973,478 tweets look like on a map, at any scale you want.

I’ve open sourced the tools I used to manipulate the data and did all the design work in Mapbox Studio. Here’s how you can make one like it yourself.

Three main steps (not including data collection): filter out noise and duplicates, generate map tiles, and style to your liking.

Motion Exposure, a photography project by Stephen Orlando, captures movement patterns with light.

I’m fascinated with capturing motion through time and space into a single photograph. Using LED lights with custom color patterns and long exposure photography, I’m able to tell the story of movement. This technique reveals beautiful light trails created by paths of familiar objects. These light trails have not been artificially created with Photoshop and represent the actual paths of the objects.

The above shows kayaking movements, which is just one of many activities including canoeing, soccer, karate, and bike polo. See it all in the Orlando’s galleries. [via Colossal]

Monochome, a new service brought to you by Rachel Binx, lets you make custom clothes printed with maps. It’s not just major cities though. No that’s for chumps. Using OpenStreetMap data, you select a location, choose the style of map, and pick your clothing item, and you’ve got your custom map print to wear. You can currently choose among a tank top, pencil skirt, flare skirt, and t-shirt.

Get your order in this week to ensure you receive your item for Christmas. Even if you’re not looking to get anything, it’s kind of fun to play around with the interface that lets you create an item.

Like many, I’ve been listening to Serial every week, but I always just listened through my podcast app. So I missed this little bit from Adnan Syed way back in the second episode. He sent the two graphs above to the host Sarah Koenig. The graphs show tea price changes over time for two stores and Syed asks Koenig which store she would get her tea from. She says the first one, which has a more steady price.

Look again, Adnan said. Right. Their prices are exactly the same. It’s just that the graph of C-Mart prices is zoomed way in — the y-axis is in much smaller cost increments — so it looks like dramatic fluctuations are happening. And he made the pencil lines much darker and more striking in the C-Mart graph, so it looks more…sinister or something.

This was Adnan’s point: See how easy it is to look at the same information, but, depending on how it’s presented, come to two different conclusions about what it means? The 7-11 graph is the “innocent” graph. The C-Mart graph is the “guilty” graph. But they contain the same information.

This pyramid pie chart just might take the pie chart humor crown from the amount-of-pie-eaten pie chart. (Who made this?)

Along the same lines as the scaled Periodic Table, Elemental Cartograms by chemistry professor Babak Sanii and his students lets you make your own scaled Periodic Table of Elements. Simply edit the provided spreadsheet, upload, and you’ve got your cartogram.

Normally, I’m not so thrilled with cartograms because of how they mess things up with shape, but that’s with geographic maps. You don’t have to worry about preserving borders so much with the Periodic Table.

Make your own or check out examples of the cartograms in use.

Inspired by a diagram from 1976, the Big Picture group at Google Research built a Periodic Table where elements are scaled based on their use in the world.

Sterling Crispin reverse engineered facial recognition algorithms and produced masks that only kind of look human. Although the computer sees it differently.

This research has resulted in the production of a series of 3D printed face masks which were algorithmically evolved to satisfy facial recognition algorithms. It is important to understand the the goal of creating these masks isn’t to defeat facial recognition or provide something undetectable, simply covering your face with your hand will do that. Rather, my goal is to show the machine what it’s looking for, to hold a mirror up to the all-seeing eye of the digital-panopticon we live in and let it stare back into its own mind.

Creepy results. [via Kyle Chayka]

Because that’s what happens when you eat ten full plates of turkey and pie. However, Bonnie Berkowitz and Lazaro Gamio for the Washington Post go into some of the specifics of holiday eating. The last bit of the feelings section (part of it shown above) on permanently heavy:

After the first 750 calories or so, your body begins to store a larger percentage of food as fat. A 2000 study found that the average adult gains a pound during each holiday season and usually never loses it.

Wait — really?

Charted is a tool used internally at Medium that they recently released into the wild. It’s for the quick-and-dirty times when you just need to see quick results.

Charted is open-sourced and available for anyone to use at charted.co. The publicly-hosted charted.co works with files that are already publicly accessible to anyone with the link (e.g., Dropbox share links). For protected or sensitive data, you can serve your own instance of Charted on your secure network, which is what we do at Medium.

It’s a stripped down charting tool built for a specific type of data, so there are of course limitations. But there’s also potential to customize for your own needs. Or if you have a simple time series that you frequently glance at, Charted might come in handy. [Thanks, Derek]

This is what you get when you cross a histogram and piano keys to show note distribution of songs. It’s the pianogram. View examples such as Fur Elise or the classic Chopsticks, or punch in your own MIDI-formatted song for a taste of the distribution ivories.

Color exists on a continuous spectrum, but we bin them with names and descriptions that reflect perception and sometimes culture. We saw this with gender a while back. Wikipedia has a short description on culture differences and color naming.

Muyueh Lee looked at this binning through the lens of English versus Chinese color naming. More specifically, he looked at Chinese color names on Wikipedia and compared them against English color names. This comes with its own sampling biases because of higher Wikipedia usage for English speakers, but when you divide by color categories, it’s a different story.
