History through the president’s words
By Kennedy Elliott, Richard Johnson and Ted Mellnik, Published: Jan. 28, 2014
Since 1900, there have been 116 State of the Union addresses, given by 20 presidents, with some presidents giving two addresses a year. Studying their choice of words, over time, provides glimpses of change in American politics—“communism” fades, “terrorism” increases—and evidence that some things never change (“America” comes up steadily, of course. As does “I.”). Wayne Fields, a professor of English and American Culture Studies at Washington University in St. Louis, and Mark Liberman, a linguist at the University of Pennsylvania, offered their analysis of the meaning behind the words the presidents used.

In flight: see the planes in the sky right now

Espantosa visualização de todos os aviões no ar, neste momento
To mark 100 years of passenger air travel, our stunning interactive uses live data to show every one of the thousands of commercial planes currently in the air, charts the history of aviation since 1914, and asks what comes next for the industry.
Kiln and the Guardian explored the 100-year history of passenger air travel, and to kick off the interactive is an interactive map that uses live flight data from FlightStats. The map shows all current flights in the air right now. Nice.
Be sure to click through all the tabs. They’re worth the watch and listen, with a combination of narration, interactive charts, and old photos.
And of course, if you like this, you’ll also enjoy Aaron Koblin’s classic Flight Patterns.

Music Timeline
Posted by Armando Brito Mendes | Filed under visualização
Mais uma excelente visualização interativa de dados dos labs da google
Two Google research groups, Big Picture and Music Intelligence, got together and made a music timeline baby.
The Music Timeline shows genres of music waxing and waning, based on how many Google Play Music users have an artist or album in their music library, and other data (such as album release dates). Each stripe on the graph represents a genre; the thickness of the stripe tells you roughly the popularity of music released in a given year in that genre. (For example, the “jazz” stripe is thick in the 1950s since many users’ libraries contain jazz albums released in the ’50s.) Click on the stripes to zoom into more specialized genres.
As you’d expect, the initial view is a stacked area chart that represents the popularity of genres over time, which feels fairly familiar, but then you interact with the stacks and it gets more interesting and almost surprisingly fast. The best part is the pointers to specific albums as you mouse over.

Lexical Distance Among the Languages of Europe
Posted by Armando Brito Mendes | Filed under Investigação Operacional, visualização
Um bom exemplo de aplicação de redes como visualização à proximidade das linguas Europeias
This chart shows the lexical distance — that is, the degree of overall vocabulary divergence — among the major languages of Europe.
The size of each circle represents the number of speakers for that language. Circles of the same color belong to the same language group. All the groups except for Finno-Ugric (in yellow) are in turn members of the Indo-European language family.
English is a member of the Germanic group (blue) within the Indo-European family. But thanks to 1066, William of Normandy, and all that, about 75% of the modern English vocabulary comes from French and Latin (ie the Romance languages, in orange) rather than Germanic sources. As a result, English (a Germanic language) and French (a Romance language) are actually closer to each other in lexical terms than Romanian (a Romance language) and French.

Century of rock history
Posted by Armando Brito Mendes | Filed under visualização
Para quem gosta de música esta visualização é extraordinária
Jessica Edmondson visualized the history of rock music, from foundations in the pre-1900s to a boom in the 1960s and finally to what we have now. Nodes represent music styles, and edges represent musical connections. There are a lot of them and as a whole it’s a screen of spaghetti, but it’s animated, which is key. It starts at the beginning and develops over time, so you know where to go and what to look at. Music samples for each genre is also a nice touch. [Thanks, Jessica]

Uso de algorimtos de visinho mais próximo para visualizar semelhanças
North Carolina State statistics graduate student Joshua Katz already mapped dialect across the United States, and now there’s a fun addition in quiz form. Answer the 25-question survey (or the more detailed 140-question version if you dare), and you get a map of language similarity. More specifically, the result maps shows the probability that someone in that area understands what you’re saying.

Visualization archives on FlowingData
Posted by Armando Brito Mendes | Filed under visualização
Os arquivos de artigos sobre visualização de dados
Download data from a site of interest and learn all you can about it. Analyze, try to answer your own curiosities, and of course, visualize it. Try to apply what you’ve learned from the books and tutorials to your own data. And I’m not gonna lie: It might be rough at first and maybe frustrating, but you’ll get there.
I gathered some resources a few years ago on where to find data. Some of the sites are dead now, but it should give you a good idea of where to get some spreadsheets and CSV files. If you’re lucky, you might find data sources in PDF format. Have fun with that.
After that, download R, mess around with a trial version of Tableau, get your Data-Driven Documents on, or even try to push Excel to the limit.
If you’re still not sure where to begin, find a visualization you like and try to reproduce it. If it’s a good one, you’ll probably discover that making the graphic is a lot harder than you expected. Totally normal. The FlowingData archive provides plenty of examples.
