SubMap 2.0: Ebulition
Posted by Armando Brito Mendes | Filed under videos, visualização
Visualização de notícias como distorções do mapa da Hungria
Ebullition visualises and sonificates data pulled from one of the biggest news sites of Hungary, origo.hu. In the 30 fps animation, each frame represents a single day, each second covers a month, starting from December 1998 until October 2010.
Whenever a Hungarian city or village is mentioned in any domestic news on origo.hu website, it is translated into a force that dynamically distorts the map of Hungary. The sound follows the visual outcome, creating a generative ever changing drone.

Wolfram|Alpha Pro: Análise automática de dados
Posted by Armando Brito Mendes | Filed under estatística, software, visualização
Análise automática de dados, será possível?
The key idea is automation. The concept in Wolfram|Alpha Pro is that I should just be able to take my data in whatever raw form it arrives, and throw it into Wolfram|Alpha Pro. And then Wolfram|Alpha Pro should automatically do a whole bunch of analysis, and then give me a well-organized report about my data. And if my data isn’t too large, this should all happen in a few seconds.
And what’s amazing to me is that it actually works. I’ve got all kinds of data lying around: measurements, business reports, personal analytics, whatever. And I’ve been feeding it into Wolfram|Alpha Pro. And Wolfram|Alpha Pro has been showing me visualizations and coming up with analyses that tell me all kinds of useful things about the data.

Van Gogh for the colorblind
After a chat with his color deficient friends about how Vincent van Gogh’s paintings seem to appeal to all eyes, Kazunori Asada used visual filters to see how the paintings looked to the colorblind. The experiment produced some interesting results and musings:
Was van Gogh partially color vision deficiency (anomalous trichromat)? Perhaps using a strong color vision deficiency (dichromat) simulation was the wrong approach. How about carrying out the simulation by removing the middle portion of normal color vision, maybe then I could see van Gogh’s pictures in a better light?
The color choices for van Gogh’s popular paintings seem less out there with the filters. The greens in the sky of Starry Night, for example turn to yellows.
A colorblind van Gogh though? Probably not. Either way, don’t forget to pick your colors wisely. Asada has an easy-to-use tool to see what your own images look like to others.

The Best Data Visualization Projects of 2011
I almost didn’t make a best-of list this year, but as I clicked through the year’s post, it was hard not to. If last year (and maybe the year before) was the year of the gigantic graphic, this was the year of big data. Or maybe we’ve gotten better at filtering to the good stuff. (Fancy that.) In any case, data graphics continue to thrive and designers are putting more thought into what the data are about, and that’s a very good thing.
So here are my favorites from 2011, ordered by preference. The order could easily scramble depending when you ask me.

When numbers are too factual
Carl Bialik, for The Wall Street Journal, reports on PSAs and the use of scary numbers:
The Ad Council usually avoids statistics in PSAs. “We know from our experience that effective advertising has to have an emotional component and statistics-based campaigns can be very rational,” Conlon said. “We’ve also found that people tend not to believe statistics.”
And sometimes they just don’t care much about them. “When we were developing our underage drinking prevention campaign,” Conlon recalled, “we found that it doesn’t resonate with parents to learn about how many children are drinking underage. It’s too easy for them to say ‘it’s not my child.’ We found that it was much more compelling to include a statistic that was more about the consequences of underage drinking: Those who start drinking before age 15 are six times more likely to have alcohol problems as adults than those who start drinking at age 21 or older.”
The well-known Stalin quote comes to mind.
