Data Viz News [72]

All the top links of the week, about visualization of information and data journalism

October 11, 2014

Welcome to another edition of “Data Viz News”, our weekly bulletin for those interested in information design, data journalism, cartography and all other things data-related. We always try to bring you the best content from around the Internet, something that has actually picked up in many blogs out there. Not so long ago, only Andy Kirk at Visualising Data and a handful of other publishers were making this sort of effort, but now, there are literally dozens that you can follow to keep up with all the content being produced on an increasing rate.

Because that’s the thing: You have more and more interesting content out there. More that we can actually digest, in many cases. Every week, new blogs are created, hundreds of articles are published, presentations are shared on YouTube, Vimeo and Slideshare, and so on. It’s no surprise that these “best of the week/month/year” types of posts continue to get some attention – and clicks -, and we’re glad they do, because no matter how hard you try, you’ll never get it all. It’s simply impossible.

So let’s move on to our “link-festival”, that includes news about data visualization competitions (including the Information is Beautiful Awards), step-by-step tutorials, interviews and in-depth discussions, and much more. And during the week, we covered both the ÑH awards and the Brazilian elections, here on Visualoop, in addition to our usual round ups of interactive infographics and maps, and exquisite examples of visual journalism and vintage charts and graphics. We also had an interview with Jason Lankow, the co-founder and CEO of Column Five Media and Visage, and a guest post by infographic master Luiz Iria – a special one for soccer fans.

In sum, a lot to read, explore and learn from, if you’re interested in visualization, cartography, data journalism and all related fields. Here are this week’s recommended links:

NEWS

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

As mentioned in the introduction, the Kantar Information is Beautiful Awards online gallery has been updated with the projects longlisted for the 2014 edition. You can also explore all the visualizations from previous years.

Using Mapbox Vector Tiles, the recently launched Surface API can look at elevation profiles to crime indices to home prices – anything, any data that you upload. The core of the API is a flexible query interface. Given a point on a mountain, it can compute the elevation at that point by interpolating nearby values. Given a line across the mountain’s ridge, it’ll return multiple elevation values along the path. A couple of examples are presented, like this bicycle theft rate density map in San Francisco that features bike theft and elevation:

Data Visualization is a great way to show off your data. It reveals patterns and trends, and can grab attention better than a table of numbers. But vision isn’t the only sense we can use to get a feel for data. Hearing can also be a great way to input data into our brains, as Drew Skaw shows in this article.

Interesting post by Jill Walker Rettberg, professor of digital culture at the University of Bergen, explaining the meaning and importance for Humanities of “dataism” – a term coined by Prof. José van Dijck, in an article she published this spring.

Data isn’t just objective information any more. It’s interpretations of our emotions, translated into numbers and graphs and rendered more reliable – more cerebrally sincere – than our own thoughts.

The latest project by the team coordinated by Lev Manovich, about visual social media, is called The Exceptional and the Everyday: 144 hours in Kiev – a continuation of previous Software Studies Initiative’s projects, phototrails.net and selfiecity – which Moritz Stefaner talked with us about here. In this new installement, using computational and data visualization techniques, the team explores 13,208 Instagram images shared by 6,165 people in the central area of Kiev during 2014 Ukrainian revolution (February 17 – February 22, 2014).
