Data Viz News [20]

The top news, articles and resources from throughout the Internet

August 17, 2013

With a Google near-unprecedented outage – it killed 40% of the entire Internet use, as reported here – and websites belonging to the Washington Post, CNN, and Time magazine being attacked by supporters of Syrian President Bashar al-Assad, this was a particularly strange week. According the BBC, that breach was the result of a security failure at a firm which provides a link recommendation service that all three sites used, and as far as the Google outage goes, it is still unclear what really happened, so we can expect further updates on that in the upcoming days.

But it’s in the Articles section, however, that the today’s list of suggested links is fully packed, ranging from vintage information graphics – great to see more and more folks revisiting the past -, to overviews and fresh insights by the likes of Alberto Cairo and Stephen Few.

Other articles, interviews and resources complete our Data Viz News number 20 – not really a big milestone, but it has been great to see the data visualization community supporting this work, so we just want to thank you all for that, before we move on to this week’s recommended links.


 

NEWS

Latest product launches and business announcements, career moves, data visualization competitions and general news.

The crisis in Syria spread to the cyberspace, with websites belonging to the Washington Post, CNN, and Time magazine being attacked by supporters of President Bashar al-Assad. Earlier this week, the Syrian Electronic Army (SEA) also hit the Facebook and Twitter accounts of the New York Post.

As mentioned in the introduction, a major outage brought down all of Google’s services, from Google Search to Gmail, YouTube, Google Drive, and beyond. Neil McAllister reports that “according to web analytics firm GoSquared, worldwide internet traffic dipped by a stunning 40 per cent during the brief minutes that the Chocolate Factory’s services were offline”. Here’s the graph of what that looked like:

According to the blog post, It’s a way of helping engineers grow and have access to world-class technical training, along with opportunities to teach the skills they’ve all mastered.

 

ARTICLES

A selection of recent articles published by experts in data visualization, cartography and programming, among other topics.

After a recent trip to Belo Horizonte (Brazil), for a keynote about information design, Alberto Cairo wrote this article stating that “today, being able to present information graphically is as important for anyone willing to communicate effectively as writing and presentation skills” -something many of you who’ve read his book or participated in one of the MOOCs he gave have known for a while.

One of world’s leading experts in data visualization for data sense-making and communication is back with another article – and soon, a new book. Stephen Few shares some of details behind Signal (the current working title), a book that will focus on analytical techniques for detecting signals in the midst of noisy data.

Data that do not convey useful knowledge are noise. When data are displayed, noise can exist both as data that don’t provide useful knowledge and also as useless non-data elements of the display

 

Robert Kosara talks about the beautiful Chart of Electromagnetic Radiations (1944) as “the kind of poster or magazine fold-out that was fairly common during the golden age of information graphics, from the 1940s (if not earlier) to the early 1990s.”

Another article about vintage information design, this one on how Da Vinci’s studies of the human body still influences the Human anatomy drawings, by Paul Hastie for BBC Arts & Culture.

Robert Simmon continues the series of articles dedicated to the use of color in data visualization. In this post, he talks about the difference between the types of data – divergent and categorical or qualitative -, and how to pick the best color palette for each one.

Google teamed up with Beyond and launched the Google Databoard, a tool focused on sharing the contents of its research reports. In this post, Bryan Connor shares his opinion about this tool, including some recommendations for its improvement.

Another data visualization review, this one by Kaiser Fung. He talks about a recent visualization published by NFL.com, that has a spider charts as the main tool. And as many of us already know, “despite being beautifully constructed, and fun to play with”, this type of chart just doesn’t work as a vehicle for communication.

This was one of those stories that made the week, at least in terms of Twitter activity and major blogs coverage. Nobutaka Aozaki, a Japanese-born, New York-based conceptual artist, has been working on a partial map of Manhattan compiled of individual, hand-drawn maps he’s collected from strangers. The artist walks up to passersby on the street and asks for directions. He’s focused on both major tourist destinations and places where he goes out to eat or to meet friends.

Manhattan has one of the worst income gaps of any city–or country–in the world, often separated by just a few blocks. Nickolay Lamm (who was behind some other great visualizations, including what our world would look like if you could see Wi-Fi, and striking pictures of how sea-level rise is going to flood iconic cities on the East and West coasts), created some impressive graphics that display that inequality in the height of the city’s buildings.

The rise of personalized data is poised to be a hot topic as companies seek to deliver real benefits from the information gathered on consumers. The challenge for designers lies in finding a way to reduce the complexity posed by such vast amounts of data and give data a human shape – the famous ‘storytelling’-, and Dominic Quigley talks about five core principals to follow when embarking on a data visualization challenge.

Crop circles aren’t really a visual representation of information, but their have a profound impact in our collective imaginary. And if they’re underwater and made by a five inches long puffer fish, well, that is just something that awakes our inner-science geek, no matter if you’re into to visualization or not. Enjoy the video, and read the article by Lisa Raffensperger.
