    Hand-drawn San Francisco map

    Maps can be about a lot of things, from strictly geography and location down to the individuals who reside in an area. Illustrator Jenni Sparks embeds herself in a city, takes copious notes, and draws detailed maps about what she learns. Her style lends to the community side of the spectrum.

  • Household incomes rise

    September 19, 2014  |  Statistical Visualization

    Income difference since 2009

    Since the recession, it's taken a while for household incomes to come back to where they were in 2009. In most parts of the country, incomes are still lower, however, it appears they are making their way back to 2009 levels. With the Census Bureau's recent release of data from their American Community Survey, the Washington Post charted the annual difference from 2009 to 2013.

    Each line represents a metropolitan area's difference in household income of a current year, compared to that of 2009. So the closer to or higher above the thin black baseline the better.

  • PhD gender gaps around the world

    September 18, 2014  |  Statistical Visualization

    How Nations Fare in PhDs by Sex

    Periscopic, for Scientific American, visualized the number of PhDs awarded in various countries. You might expect men to be in high percentages and women to be in low, but it's not always in that direction.

    In the U.S., women are going to college and majoring in science and engineering fields in increasing numbers, yet here and around the world they remain underrepresented in the workforce. Comparative figures are hard to come by, but a disparity shows up in the number of Ph.D.s awarded to women and men. The chart here, assembled from data collected by the National Science Foundation, traces the gender gap at the doctoral level for 56 nations. The situation in individual countries varies widely, but as the numbers make clear, there are interesting exceptions to the global trend.

    Each view shows a vertical dotted line to indicate where PhDs awarded are an even split between men and women. To the left of that dotted line shows where men earn more PhDs than women, and on the right, where women earn more than men.

  • Search for word usage in movies and television over time

    Data usage

    Movies and television shows often reflect cultural trends of the time they are made in. Even movies that take place during the past or future can say something about the present through metadata or production style. Benjamin Schmidt, an assistant professor of history at Northeastern University, provides a tool that lets you see trends in movie and television dialogue.

  • Powers of Ten, Derek Jeter style

    September 16, 2014  |  Infographics

    Powers of Jeter

    You've likely seen the classic Powers of Ten video from 1977. It starts on an individual and continues to zoom out farther to a view of galaxies. The video provides a sense of scale that makes really big (and really small) numbers more relatable. We're just not very good at picturing scales beyond a certain range.

    So when you hear that retired baseball player Derek Jeter took an estimated 342,000 swings during his professional career, you get that it's a lot, but only kind of. The New York Times went all Powers of Ten on the Jeter swing count to help you see better.

    The piece starts with a single swinging Jeter, and as you scroll down you get the average swings per at-bat, then practice swings per game. Keep going, and you get the career total.

    See all the Jeters.

  • Pantone beer cans

    September 16, 2014  |  Data Art

    Graphic designer Txaber created beer can labeling to match the typical color of each beverage to its Pantone color.

    Patone beer cans

    I probably wouldn't buy beer with this labeling though. Usually you look for more complexity in your beverage, and these colored cans say flat and single-noted beer to me. Fun though. And maybe useful for beer beginners. [via Boing Boing]

  • Probabilities of failing birth control methods

    September 15, 2014  |  Statistical Visualization

    Birth control effectiveness

    In high school health class, where I learned about contraceptives and the dangers of pre-marital sex, my teacher spouted rates to scare. He would say something like condoms are 98 percent effective but never explained what that meant. Do they break 2 percent of the time? Do couples get pregnant 2 percent of the time? STDs?

    These charts from Gregor Aisch and Bill Marsh might help. They show the probability of an unplanned pregnancy, categorized by contraceptive and over a span of ten years. The top solid lines represent probabilities with "typical use" and the dashed lines on the bottom represent probabilities with "perfect use."

    Maybe it's time for better instructions on how to use these things.

    Update: The calculation of long-term probabilities is likely on the pessimistic side and makes too many assumptions about the data and population. Andrew Whitby critiques.

  • Extinctions and animal species at risk

    September 12, 2014  |  Infographics

    A Disappearing Planet

    Data journalist Anna Flagg for ProPublica reported on animal species at higher risk of extinction.

    Animal species are going extinct anywhere from 100 to 1,000 times the rates that would be expected under natural conditions. According to Elizabeth Kolbert's The Sixth Extinction and other recent studies, the increase results from a variety of human-caused effects including climate change, habitat destruction, and species displacement. Today's extinction rates rival those during the mass extinction event that wiped out the dinosaurs 65 million years ago.

    The data has an interesting organization. Think back to sixth-grade science and remember that animals are grouped in a hierarchy of order, family, genus, and species. This hierarchy is represented with horizontal bars on the bottom, vertical line pointers, vertical bars, and elements within each bar, respectively.

    Once you get down to the genus level (vertical bars), the interactive gets kind of tough to use unless you search for a specific species. I want some filters or some breakout sections to highlight spots to look at. However, as a tool for those closer to the challenge, this seems like it could be quite useful.

  • Generative book covers

    Generative book covers

    The New York Public Library is developing an eBook-borrowing system, which includes an app that helps you keep track of books, process, and such. One of the challenges is displaying the covers of available books when many of the works don't actually have a cover, so NYPL Labs turned to generative covers that could be made on the fly. Mauricio Giraldo Arteaga, in charged of design, explains the process.

    The code for iOS and Processing is available on GitHub.

    Dinosaurs versus airplane

    Scientists found the fossils of a giant dinosaur that they estimate was 26 meters long and 60 tons heavy. How much is that really? BBC News provided a simple chart to put size into perspective. They compared dinosaur sizes to a moose, African Elephant, and a Boeing 737-900.

    Impressive. Although not as impressive as Mega Shark. [Thanks, Jim]

  • Old maps overlaid on Google Maps

    Old maps overlaid on Google Maps

    The British Library georeferencing project places old maps, as far back as the 16th century, on top of Google Maps for browsing and as a mode of comparison.

    The British Library began a project to crowdsource the georeferencing of its scanned historic mapping in 2011 by partnering with Klokan Technologies to customise its online georeferencing tool. There have been five public releases of maps since 2012, all of which met with tremendous success. In total over 8,000 maps have been "placed" by participants and subsequently checked for accuracy and approved.

    Has someone else done this? I feel like I've seen something like this project before, but the closest thing I can think of is Historypin, which overlaid images on top of Google Streetview.

  • Style over function for redesigned choking posters

    Escape from Choking in New York by Phil Ashworth

    In many parts of the country, the departments of health require that eating establishments put up posters that instruct you what to do in case someone is choking. The posters are government-issued, but some people are putting up redesigned posters that fit in with restaurant decor. The Sideshow Podcast covers the trend and some of the ridiculous posters to come out of it.

  • Cosmic map shows Milky Way at the edge of a supercluster

    September 4, 2014  |  Mapping

    Nature highlights the research of R. Brent Tully et al, which defines a supercluster called Laniakea. A supercluster is like a network of galaxies, and according to this work, the Milky Way is at the edge of this one.

    From the abstract:

    Here we report a map of structure made using a catalogue of peculiar velocities. We find locations where peculiar velocity flows diverge, as water does at watershed divides, and we trace the surface of divergent points that surrounds us. Within the volume enclosed by this surface, the motions of galaxies are inward after removal of the mean cosmic expansion and long range flows. We define a supercluster to be the volume within such a surface, and so we are defining the extent of our home supercluster, which we call Laniakea.

  • Race distributions of police departments versus residents

    September 4, 2014  |  Infographics

    Race Gap in Police Departments by NYT

    When you compare distributions of race for police departments and for the residents of the area they serve, you find disparity in many metropolitan areas. Jeremy Ashkenas and Haeyoun Park for the New York Times report, focusing on the higher percentage of white police officers.

    Stacked bars show race distributions for residents (top) and the respective police department (bottom) for selected cities. A map for each area shows bubbles colored by amount of gap and sized by number of police officers. The darker the shade of green, the bigger the gap, so you see mostly green maps.

  • When people work, by job category

    September 4, 2014  |  Statistical Visualization

    When people work

    In another use of data from the American Time Use Survey, Planet Money looks specifically at the hours people work, separated by twenty job categories. Each density area represents a category, and height represents the percentage of people (estimated with survey answers) who are at work at various hours of the day.

    The interesting bit is that you can select two job categories to easily compare at once. For example, the above shows transportation in yellow against protective services in blue. For the latter, you see a more spread out distribution, as it's more common for those in protective services to work at night.

    Make your own comparisons.

    The stacked area chart from the New York Times from almost six years ago (whoa, time) is still my favorite visualization of the survey data.

  • Segregated schools, still

    September 3, 2014  |  Mapping

    Share of white kids attending majority-white schools

    The map above by MetroTrends shows the percent of white kids who attended majority-white schools during the 2011-12 school year. Schools are still segregated in many areas of the country.

    From Reed Jordan for MetroTrends:

    The separation of races is most clearly seen in large metropolitan counties that hold the bulk of a state’s population and most of its students of color. For example, in Chicago (Cook County), the overall student population is about 25 percent white, 31 percent black, and 37 percent Latino, but 96 percent of black students attend majority non-white schools and 67 percent of white students attend majority white schools. In other words, white students tend to attend schools with other white students and black and Latino students attend schools with other students of color.

    Estimates are from the National Center for Education Statistics. [via @datatelling]

  • Louisiana is drowning

    August 29, 2014  |  Mapping

    Losing Ground by Propublica

    Louisiana is quickly losing much of its coast to the Gulf of Mexico. ProPublica and The Lens just launched an interactive project that shows you by how much and tells the story of those affected.

    In 50 years, most of southeastern Louisiana not protected by levees will be part of the Gulf of Mexico. The state is losing a football field of land every 48 minutes — 16 square miles a year — due to climate change, drilling and dredging for oil and gas, and levees on the Mississippi River. At risk: Nearly all of the nation's domestic energy supply, much of its seafood production, and millions of homes.

    There is a lot to look at and learn about, but the most telling is when you zoom in to specific regions indicated by squares on the map. Use the timeline that appears at the top of the map to see how the coastline, based on satellite imagery, has diminished since 1932. It's disconcerting.

  • Interactive tool shows impact of terrorism

    August 28, 2014  |  Infographics

    A World of Terror by Periscopic

    The Global Terrorism Database, maintained by the University of Maryland, is an open source database that catalogs terrorism events since 1970 through 2013. Data visualization firm Periscopic visualized the incident-level data in A World of Terror.

    There are over 3,065 organizations and groups listed in the GTD. To identify the top 25 organizations who used terrorist tactics, we determined the groups with the most killings, the most wounded, and the most incidents. We wanted to make sure we were inclusive of all actions, including those that neither wounded nor killed. We aggregated these 3 lists and took the top 25 organizations (most were in the top 30 for all 3 categories). These top 0.8% of groups account for over 26% of the 125,087 incidents.

    The midsection of each group shows number of incidents by month and year. The darker the brown, the more incidents on record. Then on the top and bottom shows number of people killed in red and wounded in orange, respectively. Finally, click on the map in the top left for more information about the organization.

    Spend some time with this one. Periscopic shows a lot without it ever feeling like too much.
