Never trust a statistic that you haven’t visualized yourself. It’s election time in Germany and, as usual, there are tons of opinion polls telling us who is going to win the election anyway. It is debatable whether or not pre-election polls are healthy for our democracy in general, but at least everybody agrees that the polls should be kind of neutral. And if they are not, the institutes publishing the polls should be blamed publicly. But how do we know if an institute publishes ‘biased’ polls? You guessed it: with data.

chartsnthings 19 Sketches of Quarterback Timelines On Sunday Eli Manning started his 150th consecutive game for the Giants, the highest active streak in the NFL and the third-longest streak in NFL history. (One of the other two people above him is his brother, Peyton.) The graphics department published an interactive graphic that put Eli’s streak in the context of about 2,000 streaks from about 500 pro quarterbacks. Data Visualization: 4 Swingin’ Infographics Data Visualization: 4 Swingin’ Infographics Data visualization has become an active area of research, teaching, and development. In this series, I will showcase every week some of the most creative infographics and data visualization examples. This first installment will feature four beautiful and creative infographics that we found very inspiring. Enjoy the journey!

Let’s Crowdsource a Database of Websites about Data Journalism! While doing research for a PhD on data journalism in Brazilian newsrooms, I have recently stumbled upon the need to analyse what reporters and researchers abroad are talking about the subject. But I was soon after confronted with the absence of a comprehensive database or other resource listing websites and weblogs on visualization, investigative techniques, CAR, and all other newsrooms practices labelled as data journalism. So, using a humble Google Docs spreadsheet, I started one. Data journalism is big in Brazil right now, and there is a fair number of reporters sharing techniques and discussing the recently sanctioned Freedom of Information law. One of them is CAR pioneer José Roberto de Toledo, who writes Vox Pública and is the head of the data team at O Estado de São Paulo. Marcelo Soares, another CAR evangelist, works at Folha de São Paulo and is the author of Afinal de Contas.

Slides, Tools and Other Resources From the School of Data Journalism 2013 The School of Data Journalism, Europe's biggest data journalism event, brings together around 20 panelists and instructors from Reuters, New York Times, Spiegel, Guardian, Walter Cronkite School of Journalism, Knight-Mozilla OpenNews and others, in a mix of discussions and hands-on sessions focusing on everything from cross-border data-driven investigative journalism, to emergency reporting and using spreadsheets, social media data, data visualisation and mapping for journalism. In this post we will be listing links shared during this training event. The list will be updated as the sessions progress. If you have links shared during the sessions that we missed, post them in the comments section and we will update the list.

Javascript and SVG: Back to the Future Happy New Year! One of the things I am looking forward to in 2012 is yet more improvements in the no-longer-humble web browser. The move towards ‘web apps’ has made browser manufacturers focus on the speed at which users can interact with a page (usually this is done via javascript). This has brought with it remarkable improvements to the usability of complex, interactive data graphics. By way of example, I’d point you to the following page, making sure you are using a modern browser (Google Chrome, Firefox, Safari or IE9+). The graphic uses open SVG (Scalable Vector Graphics) content (not Flash) to show an interactive map of commuting patterns within Greater London (just mouseover the map to see dynamically-generated ‘flows’) Latest As I mentioned in my previous post, our collaboration with the Sabeti Lab is aimed at creating new visual exploration tools to help researchers, doctors, and clinicians discover patterns and associations in large health and epidemiological datasets. These tools will be the first step in a hypothesis-generation process, combining intuition from expert users with visualization techniques and automated algorithms, allowing users to quickly test hypothesis that are “suggested” by the data itself. Researchers and doctors have a deep familiarity with their data and often can tell immediately when a new pattern is potentially interesting or simply the result of noise. Visualization techniques will help articulate their knowledge to a wider audience. This time around I will describe a quantitative measure of statistical independence called mutual information, which is used to rank associations in the data. -log 1/1000 = log 1000 = 6.9
