Rencontre avec David McCandless » Article » OWNI, Digital Journalism Le journaliste du Guardian tient le site "Information is beautiful", sur lequel il met en scène toutes sortes de données. Entretien autour des problématiques que pose la visualisation de données. Boire un thé avec David McCandless d’Information is beautiful quand on s’intéresse à la visualisation de données revient un peu à partager un pétard avec ses rockers préférés quand on est une groupie. Je souris béatement tandis qu’il peste contre sa nouvelle maison qu’il juge bien trop grande et trop froide. David met de l’eau à bouillir et je remarque que même sa théière est recouverte d’une petite laine. Quelques instants plus tard, je le suis, sans sucre et sans lait, dans les escaliers qui mènent à son bureau. Work In progress Là, il me montre une infographie sur les exoplanètes qu’il termine actuellement pour The Guardian. La notion d’échelle est fondamentale pour moi ; je crois que c’est véritablement la clé de la visualisation de données car elle donne à la fois le contexte et le sens.
50 Great Examples of Data Visualization Wrapping your brain around data online can be challenging, especially when dealing with huge volumes of information. And trying to find related content can also be difficult, depending on what data you’re looking for. But data visualizations can make all of that much easier, allowing you to see the concepts that you’re learning about in a more interesting, and often more useful manner. Below are 50 of the best data visualizations and tools for creating your own visualizations out there, covering everything from Digg activity to network connectivity to what’s currently happening on Twitter. Music, Movies and Other Media Narratives 2.0 visualizes music. Liveplasma is a music and movie visualization app that aims to help you discover other musicians or movies you might enjoy. Tuneglue is another music visualization service. MusicMap is similar to TuneGlue in its interface, but seems slightly more intuitive. Digg, Twitter, Delicious, and Flickr Internet Visualizations
How to Use the Ngram Viewer - Google Books Here's one of Google's more obscure tools. "Google Books Ngram Viewer" -- Say that ten times fast! What the heck is an Ngram anyway? An Ngram, also commonly called an N-gram is a statistical analysis of text or speech content to find n (a number) of some sort of item in the text. It could be all sorts of things, like phonemes, prefixes, phrases, or letters. In the case of Google Books Ngram Viewer, the text to be analyzed comes from the vast amount of books Google has scanned in from public libraries to populate their Google Books search engine. How does it work? Go to Google Books Ngram Viewer at books.google.com/ngrams. What is it showing you? Google Books Ngram Viewer will output a graph that represents the use of a particular phrase in books through time. Here's a real life example. Did nobody talk about vinegar pies the rest of the time? Advanced Searches Remember how I said that Ngrams could consist of all sorts of different text searches?
Sightsmap End the War on Drugs Update June 5 2011We did it! Last week Avaaz Executive Director Ricken Patel hand-delivered our over half a million signatures to the UN Secretary General Ban Ki Moon, world leaders and the global media in New York. At the meeting Ban Ki Moon heard our call to action and agreed to create a new UN task force to develop a comprehensive approach to drugs and organized crime. Update June 1 2011 Amazing! Posted May 30 2011In 72 hours, we could finally see the beginning of the end of the ‘war on drugs’. Experts all agree that the most sensible policy is to regulate, but politicians are afraid to touch the issue. This could be a once-in-a-generation tipping-point moment -- if enough of us call for an end to this madness. For 50 years current drug policies have failed everyone, everywhere but public debate is stuck in the mud of fear and misinformation. Powerful lobbies still stand in the way of change, including military, law enforcement, and prison departments whose budgets are at stake.
Ebook : le cahier de l’OpenData 2010 » Article » OWNI, Digital Journalism Acteur du datajournalism, Owni suit de près le mouvement open data. Les fortunes sont diverses selon les pays. Retour sur les avancées et les reculs de l'année 2010 en dix articles. «Nous ouvrons les gouvernements» : si le slogan de WikiLeaks semble voir été entendu, au moins en partie par les gouvernements anglo-saxons, comme en témoignent les initiatives des Etats-Unis, de la Grande-Bretagne, de l’Australie et du Canada, la majeure partie des pays restent à la marge. Ainsi, les pays européens peinent à suivre le mouvement de l’open data, malgré la mise en place de la directive européenne INSPIRE en 2007, et la France ne déroge pas à cette règle. Les politiques nationales, conservatrices en la matière, ont peu évolué depuis la loi du 17 juillet 1978 et restent aujourd’hui contradictoires et inégales selon les secteurs, orientées parfois vers un mouvement de fermeture, comme en témoigne la récente loi Loppsi2.

Web Trend Map 2007 Version 2.0 by Oliver Reichenstein We have done it before: the 200 most successful websites pinned down on the Tokyo Metro Map, ordered by category, proximity, success, popularity and perspective. Now we have done it again — and better. Back by popular demand: here is iA’s next Web Trend Map: Download It! We figured that this would make a nice desktop background image as well. What’s New? First of all, the new Trend Map features many more websites than the previous one. More Consistency The different trend lines have been renamed, simplified and cleaned up. More Lines The original raster (Tokyo metro map) has been substantially modified to fit the needs of an Internet Trend Map. Less Japanese Jokes There are less insider jokes about the different stations and more consistency between the connections and the neighborhoods of the different sites. Google has moved from Shibuya, a humming place for young people, to Shinjuku, a suspicious, messy, Yakuza-controlled, but still pretty cool place to hang out (cf.
Google's Ngram Viewer Goes Wild - Ben Zimmer With the addition of wildcard search-term capabilities, Google's fabulous language-analysis tool gets even more powerful. It's been nearly three years since Google rolled out its Ngram Viewer, allowing armchair historians to plot the trajectories of words and phrases over time based on an enormous corpus of data extracted from the Google Books digitization project. Since then, there have been numerous studies seeking to glean some cultural significance from the graphs of falling and rising word usage. As the Ngram model extends its influence, Google continues to tinker, making improvements to the Ngram Viewer's already slick interface. Anyone who has spent time delving into databases knows how much flexibility you can get with wildcards: use an asterisk to stand in for any word, and suddenly your search horizons have expanded. You can also compare different slices of the overall dataset. All of this wildcard goodness isn't restricted to the English section of the corpus, either.

Ten Fatal Flaws in Data Analysis | Stats With Cats Blog 1. Where’s the Beef? In a way, the worst flaw a data analysis can have is no analysis at all. 2. If there were to be a fatal flaw in an analysis, it would probably involve how well the samples represent the population. 3. Sometimes the population is real and well defined, but the samples don’t represent it adequately. 4. The number of samples always seems to be an issue in statistical studies ( 5. Most people don’t appreciate variance. 6. NASA uses checklists to ensure that every astronaut does things correctly, completely, and consistently. 7. If a statistical test is conducted in a study, false positives and false negatives can be controlled, or at least, evaluated. 8. Here’s where you have to use your gut feel. 9. Make sure the data spans the parts of the variable scales about which you want to make predictions. 10. Any Questions? Read more about using statistics at the Stats with Cats blog.
