Online maps that we use for directions use the Mercator projection, and this tends to dictate how we perceive the size of countries and continents. If you look at the world map on Google, for example, Africa doesn’t look that much bigger compared to China or the United States. In reality though, it’s a lot bigger. Kai Krause scales countries by their area in square kilometers and then fits them into a Africa’s borders for some perspective.

This one’s for you, cartographers. What do you think?

In case you’re on the market for a data sciencey type job, there were a number of them posted to the forums this past week, along with some other schtuff.

SEM infographics freelance — Working is picking up and I need help covering all my client requests for SEM infographics…

Designer needed for animated cartogram — I am a financial publisher in need of a designer to create a cartogram of world GDP growth by nation…

Data Visualization and Charting Business Manager — Bloomberg is looking for a passionate, experienced individual to join the Charts, Technical Analysis and Graphics Business…

Data Visualization Genius — Young, fast-growing digital media startup seeks data visualization or UI expert…

Interaction Designer — Do you believe, in a freshman-year kind of way, that design just might save the world?

P.S. I changed the “Finding a Job” forum to “Job Board” since that’s basically what it’s used for. Are you an employer looking for a qualified data person? Post it to the board. It’s free.

In their continuation of what online marketers know about you, the Wall Street Journal reports on groups scraping pages and services to reveal identities and link pseudonyms to real names. “Social networks are becoming the new public records.” My rule of thumb: if I put anything on the Web, I’m assuming it’s public.

I’m not sure who made the static version above, but here is an equivalently amusing animated version below. The Dark Knight likes to keep things fresh. [CollegeHumor]

President Obama will be answering questions live at a youth town hall today at 4pm EST, with livestreaming on MTV, BET, and CMT. He’ll be taking questions from the audience and possibly from Twitter. If you want to keep track of the conversation, the folks at Stamen have got your back with their visual Twitter tracker:

The visualization is online here, and builds on work that was previously battle-tested at the 2010 Video Music Awards. The idea is that you post messages to twitter with the #ask hashtag, followed by the issue you’re interested in asking the President about. If it’s a good one, he may answer it on the air.

Like the VMA visualization, topics are tracked and ordered by popularity. But instead of showing celebrities, this one shows issues that people on Twitter care about. A bar chart on the bottom left shows trends over time.

Neil Irwin and Alicia Parlapiano of The Washington Post report with this interactive graphic on why it doesn’t feel like we’re in a recovery:

The nation’s economic woes boil down to this. Compared with a healthy economy, about 7 million working-age people and 5 percent of the nation’s industrial capacity are sitting idle, not producing what they could. The economy is growing again, but at a rate — less than 2 percent in recent months — that’s too slow to keep up with a population that keeps increasing and workers who keep getting more efficient.

A step-by-step guide explains the output gap, the difference between potential and actual output.

In reference to the wall between reporting data and understanding it, Martin Theus proposes a different one:

Once you start to explore the data, the whole thing stops to be linear but gets to be very iterative, jumping over the wall every now and then. I.e., you may find out that the data cleaning is insufficient, or the model you have in mind needs some other transformation of the data, or you might want to collect additional or other data altogether.

The wall does exist, but I think it is more separating two kinds of people / thinking.

Theus finishes:

One thing is for sure: we won’t succeed if analysts continue to build useful but technically insufficient tools and computer scientists still build fancy tools that merely help the analysts.

Or even better: analyst and tool builder become the same person. That’ll take much longer though, so communication is a good place to start.

In collaboration with NBC News and The Gates Foundation, Ben Fry-headed Fathom Design shows you how K-12 schools measure up in your area. If you’re a parent or soon-to-be parent considering a move, this will be especially interesting to you. The Education Nation Scorecard lets you search for your location or a specific school to see how they perform and how they compare to the rest of the country.

Thousands of people flee their country every year, and the travel patterns are by no means easy to understand. Christian Behrens, in a revamp of a class project, visualizes these refugee movements with three views. The first is a circular network diagram (above), where each slice represents a region or country. Lines represent flight and expulsions.

Online dating site OkCupid dives into their data for 3.2 million users again, this time to explore gay and straight stereotypes. Many are false. Some are true. Among the findings: who’s gay curious in the United States and who thinks the earth is bigger than the sun.

In a follow up to code_swarm, a visualization to show the development of software projects, Michael Ogawa has another look with Software Evolution Storylines:

My previous software visualization experiment, code_swarm, turned out pretty good. But some wanted a more analytic view of the data — one that was more persistent. I wondered about what this could look like, and came across this XKCD comic. It represents characters as lines that converge in time as they share scenes. Could this technique be adapted for software developers who work on the same code?

The difference between this and the xckd comic is that instead of fictional characters, there are now developers, and instead of characters crossing paths, developers cluster when they work commit changes to the same file. The histogram on the bottom provides information on the type of files that were committed during any given time. Roll over any line to focus on a specific devleoper.

It seems like all the mobile groups are suing each other these days. Who’s suing whom? What company is suing the most? Who’s getting sued the most? There was a mini-wave of graphics last week to help answer these questions.

Matt Parker explains why no one should be fooled by a misuse of statistics just like no one was fooled by “I did not have sexual relations with that woman.”

This guide on how to order dim sum is missing a lot food items, but gosh darn it, I love me some dim sum. Steamed and fried goodness on the cheap is what it’s all about. One small but very important thing I would change is that last bit. There is no such thing as, “Are you still hungry?” It should be, “Can you eat anymore?” When you feel like you can’t eat anymore, you eat a little more, and then fight over the check.

Everyone’s fascinated with animated graphics, which is cool, but sometimes a series of a whole bunch of maps is just as good. Archie Tse of The New York Times shows the spread of oil over time as several static maps to complement the animated version. Nice, right? You can see the changes from start to finish at a glance.

In his five-minute TED talk (below), Gary Wolf describes the quantified self and why it matters:

The self isn’t the only thing. It’s not even most things. The self is just our operations center, our consciousness, our moral compass. So if we want to act more effectively in the world, we have to get to know ourselves better.

And with personal data stuff like Nike+ and Fitbit doing well, there’s clearly an interest (and a market for it). At what point though does personal data become too much?

xkcd + numbers on online communities. Need I say more? Along the same lines as the Web 2.0 Points of Control, xkcd maps online communities with fictitious regions sized by the amount of daily social activity. Beware of the Bay of Flame in the Blogosphere and the Northern Wasteland of Unread Updates in Facebook. Personally, I like to hop between the Twitter and YouTube islands.

It’s most interesting when you compare it to the 2007 map where MySpace, Yahoo, and Windows Live ruled the land. I guess things are a little different nowadays.

Make sure you check out the large version.

Cartography group Axis Maps continues their run of mapping goodness with the announcement of their typographic maps:

Created as a labor of love, these unique maps accurately depict the streets and highways, parks, neighborhoods, coastlines, and physical features of the city using nothing but type. Only by manually weaving together thousands upon thousands of carefully placed words does the full picture of the city emerge. Every single piece of type was manually placed, a process that took hundreds of hours to complete for each map.

Prints are available. Grab the large size for maximum goodness. They only have maps for Boston and Chicago right now, but hopefully the project continues to more cities. I’ll be keeping an eye out for San Francisco.
