Based on a column by Tim McEown, the animated video Modern Love by Freddy Arenas elegantly illustrates a relationship.
Sir Francis Galton, creator of the concept of correlation and regression toward the mean, wrote a letter to the editor of Nature in 1906 on the best way to cut a circular cake. The result is moist cake with every slice, even if you eat it days later. Alex Bellos for Numberphile demonstrates in the video below.
I don't get it. I typically just eat a full cake in one sitting with a really big fork.
According to the U.S. census, the mean center of the population shifted west every decade since 1790. They show the change in a simple animation.
The mean center of population, traditionally referred to as simply the center of population, is provided for the 2010 Census and each census since 1790. In 2010, the mean center of population was located at 37°31'03" North latitude, 92°10'23" West longitude in Texas County, Missouri, 2.7 miles northeast of Plato, Missouri.
The inclination might be to read this as people moving west, which is partially true, but don't forget immigration increasing the populations too.
Visits, a research project by Alice Thudt, Dominikus Baur, and Sheelagh Carpendale from the University of Calgary, is an exploration of your personal location history.
With visits you can browse your location histories and explore your trips and travels. Our unique map timeline visualization shows the places you have visited and how long you have stayed there. Add photos from Flickr to your visits and share your journey with your family and friends!
Visits works with geo-tagged Flickr albums, data from Openpaths and Google Location Histories. It runs locally in your browser, so no sensitive data is uploaded to our servers. When you share your history, it is up to you how much detail visits reveals and what remains private.
Simply plug your data in and explore short trips or even better, look at long-term location memories. The focus is less on analytics and numbers and more on helping you remember where you've been. [Thanks, Dominikus]
Based on estimates from the National Center for Education Statistics, Randy Olson plotted the percentage of bachelor degrees conferred to men in the United States, by major. Start your eyes at the 50% line and work your way up (more men) or down (more women).
See also the inverted version that shows the percentage of degrees conferred to women.
Nobody asked for it, so you got it. The meme package for R by Thomas Leeper lets you create the web's most popular memes in a line of code. Enjoy.
The Upshot posted an interesting chart that shows changing employment rate by state.
It shows that the economy is improving. Employment rates have climbed above the post-recession nadir in every state, although the improvements are often quite small. In Mississippi, the employment rate is just 0.1 percent above its recent low.
It also shows that the recovery has a long way to go. Employment rates have rebounded in some states with strong growth, like Utah, Nebraska and Montana. But only three states — Maine, Texas and Utah — have retraced more than half their losses.
You usually see this data presented as a time series chart, but this graphic focuses on three points of interest: employment rate at the start of the recession, the lowest rate, and the current. The rate is presented on the horizontal axis, so you see a cane-like shape that represents how far each state fell and how much farther they have to go.
I like this one. See the full graphic here.
Sharing the same collaborative principles as OpenStreetMap, a wiki-based map for the real world, OpenGeofiction is an experiment in mapping an imaginary world.
Opengeofiction is a collaborative platform for the creation of fictional maps.
Opengeofiction is based on the Openstreetmap software platform. This implies that all map editors and other tools suitable for Openstreetmap can be applied to Opengeofiction as well.
The fictional world of Opengeofiction is thought to be in modern times. So it doesn't have orcs or elves, but rather power plants, motorways and housing projects. But also picturesque old towns, beautiful national parks and lonely beaches.
As you zoom in to the map, you can see many details, from roads, bodies of water, to greenery, have already been added. Some areas look like densely inhabited cities connected by highway, whereas others are miles of forest and nature.
Browse long enough and you forget you're looking at a fake world.
New Scientist quickly covers three theories of space and time in an informational video.
— When you deal with data, you can think like a statistician, even if you don't know the math (although it will certainly help a lot). Jonathan Stray brings up fine points to draw conclusions from data, as does Jacob Harris in a detailed case study on distrusting your data.
— Learning data science still seems like a fuzzy, abstract idea. Trey Causey offers advice on getting started with the bubbling field.
— Is college still worth it? Yes.
— Coding isn't easy. If it were, everyone would do it.
— R gotchas.
I'm not sure how I just came across this now, but the Truth Facts comic by New Creations is right up my alley. It's essentially a collection of charts and illustrations that finds humor in mundane, everyday stuff. I've felt the above all too well.
I liked this sports bar name generator too.
Lots more in the archive.
For a graduate project, Michael Barry and Brian Card explored the Boston subway system through a set of annotated interactives that show train routes, usage, and scheduling.
Through publicly available data, we have the tools to understand the subway system better than we ever have before. We have seen how the system operates on a daily basis, how people use the system, how that affects the trains and also how this ties back to your daily commute. To see a real-time version of this data, check out mbta.meteor.com for up-to-the-minute congestion and delay information.
I like how they keep a subway map in view throughout. It helps you efficiently figure out what each chart means and is a good common factor as you move through the facets.
Drew Roos made a thing that lets you move the poles of the Mercator projection to anywhere in the world.
As you probably know, map projections all have their pros and cons since there are challenges that come with transforming a globe onto a two-dimensional surface. The Mercator projection, one of the most well-known, distorts as you approach the poles. The scale approaches infinity actually, which is why we're used to seeing a Greenland that is bigger than Africa. (It's not.)
Above shows the pole shifted to Washington, D.C. Trippy.
Edyn, a new project on Kickstarter, aims to make gardening easier by tracking water and soil conditions and automatically adjusting water schedules based on the data.
Edyn is there to take the guesswork out of gardening. Inserted in the soil, the Edyn Garden Sensor gathers and analyzes data about changing weather and soil conditions. The Edyn App displays this data as a real-time snapshot of your garden, and pushes alerts and suggestions to maximize plant health. A separate component, the Edyn Water Valve, uses the data collected by the sensor to smartly control your existing watering system, watering your plants only when needed.
I want this for lawns.
There are a lot of fake, spammy accounts on Twitter that come in a variety of forms. Some tweet links to junk, some serve as retweet and faving bots, and others exist purely to boost follower counts. Gilad Lotan, a data scientist at betaworks, was curious about that last type, so he bought 4,000 followers for five bucks and looked closer at his new found friends.
Jeremy Ashkenas and Alicia Parlapiano for The Upshot just plopped this interactive sucker on to the web. Each line shows change in job count for an industry. Horizontally, they're organized by average salary, and vertically, they're organized by relative change since the end of the recession. Green represents growth and red represents decline.
My initial reaction was along the lines of what-the-heck, but then you see the axes and get the mouseover actions for details. Scroll down, and you get highlighted subsets. By the end, you've learned something.
The gross domestic product for the United Kingdom rose by 5% seemingly overnight, after spending on cocaine and prostitution was (roughly) accounted for. Naturally there's been a bit of fuss over the new estimate. Tim Harford explains why the new count isn't such a travesty.
We need to understand three things about gross domestic product statistics. First, GDP itself is ineffable — an attempt to synthesise, for practical purposes, something that defies description. Second, the national accounts are not designed to give a round of applause to the good stuff and a loud raspberry to the bad stuff. They are supposed to measure economic transactions. And, third, anyone who thinks politicians try to maximise GDP has not been paying much attention to politicians.
After you read that, it's also worth listening to the Planet Money podcast on GDP from a few months back. Fuzzy estimate.
Football players are getting bigger. Noah Veltman, a developer for the WNYC Data News team, shows by how much through an animated heatmap. Scrub the slider back and forth quickly for maximum effect.
In the beginning, the league clustered in the bottom left. No one was over 300 pounds, and everyone was 6 feet and 4 inches tall or shorter. These days, player height weight are spread out more and shifted towards the top right.
