Comment la dataviz aide à comprendre la crise du logement

Vous pouvez toujours partager des tableurs remplis de chiffres compliqués, mais le résultat risque d’être décevant et surtout barbant. Pour rendre ces statistiques économiques et sociales captivantes, les « dataviz » (visualisation de données) leur ont donné une nouvelle allure. En variant les couleurs, les tailles, de façon automatique ou à la main, les journalistes et les graphistes ont multiplié les tentatives pour transformer l’austérité des données en visuels compréhensibles d’instinct.

What is data journalism?

Share on Tumblr One of the explicit connections I’ve made over the years lies between data-driven investigative journalism and government or corporate accountability.

Oakland Police Beat applies data-driven investigative journalism in California

In debugging the backlash to data journalism, I highlighted the work of The Los Angeles Times Data Desk, which has analyzed government performance data for accountability, among other notable projects. I could also have pointed to the Chicago Sun-Times, which applied data-driven investigative methods to determine that the City of Chicago’s 911 dispatch times vary widely depending on where you live, publishing an interactive map online for context, or to a Pulitzer Prize-winning story on speeding cops in Florida.

This week, there’s a new experiment in applying data journalism to local government accountability in Oakland, California, where the Oakland Police Beat has gone online. Oakland Police Beat is squarely aimed at shining sunlight on the practices of Oakland’s law enforcement officers.

Formation Courrier Picard. Why Is Data Journalism Important? Filtering the Flow of Data When information was scarce, most of our efforts were devoted to hunting and gathering.

Why Is Data Journalism Important?

Now that information is abundant, processing is more important. We process at two levels: (1) analysis to bring sense and structure out of the never-ending flow of data and (2) presentation to get what’s important and relevant into the consumer’s head. How to Teach a Journalist Programming. Earlier this year I set out to tackle a problem that was bothering me: journalists who had started to learn programming were giving up.

How to Teach a Journalist Programming

They were hitting a wall. In trying to learn the more advanced programming techniques - particularly those involved in scraping - they seemed to fall into one of two camps: People who learned programming, but were taking far too long to apply it, and so losing momentum - the generalists. People who learned how to write one scraper, but could not extend it to others, and so becoming frustrated - the specialists. In setting out to figure out what was going wrong, I set myself a task which I have found helpful in taking a fresh perspective on an issue: I started writing a book chapter. The nice thing about writing books is that they force you to put together a coherent and complete narrative about an entire process. Journalists - become data literate in three steps. Open data journalism. Data is everywhere: from governments publishing billions of bytes of the stuff, to visual artists creating new concepts of the world through to companies building businesses on the back of it.

And everyone wants to be a data journalist too - the barriers for entry have never been lower as free tools change the rules on who can analyse, visualise and present data. Truly, anyone can do it. At the same time, journalism has undergone a transformation; it's not that long ago that the only way to get a story published by a major news organisation involved years of training and interning and generally slaving away until you get noticed and published. Now, the power has shifted and the days when journalists could shut themselves away from the world in order to hand out gems of beautiful writing have well and truly vanished. These are the days of open journalism, reporters who can use the power of the web can produce stronger, better stories. Le journalisme « hacker »

Data journalist handbook project. Rating: 5.0/5 (1 vote cast) By Federica Cocco Ravensbourne college is an ultramodern cubist design school which abuts the O2 arena on the Greenwich peninsula. It is perhaps an unusual and yet apt setting for journalists to meet. Members of the Open Knowledge Foundation and the European Journalism Centre saw this as a perfect opportunity to herd a number of prominent journalists and developers who, fuelled by an unlimited supply of mocacchinos, started work on the first Data Journalism Handbook.

The occasion was the yearly Mozilla Festival, which acts as an incubator to many such gatherings. The manual aims to address one crucial problem: “There are a lot of useful resources on the web,” Liliana Bounegru of the EJC said, “but they are all scattered in different places. In the age of big data, data journalism has profound importance for society. The promise of data journalism was a strong theme throughout the National Institute for Computer-Assisted Reporting’s (NICAR) 2012 conference. In 2012, making sense of big data through narrative and context, particularly unstructured data, will be a central goal for data scientists around the world, whether they work in newsrooms, Wall Street or Silicon Valley. Notably, that goal will be substantially enabled by a growing set of common tools, whether they’re employed by government technologists opening Chicago, healthcare technologists or newsroom developers.

At NICAR 2012, you could literally see the code underpinning the future of journalism written – or at least projected – on the walls. “The energy level was incredible,” said David Herzog, associate professor for print and digital news at the Missouri School of Journalism, in an email interview after NICAR.
