On Journalism.co.uk Alastair Raid wrote about the launch on next summer of Trooclick an automatic fact-checking Firefox plug-in which will be able to verify the foundation of an article when a user reads it.

Data Stories

Few days before the European elections day Simon Rogers published a map of the United Kingdom with geotagged tweets mentioning the political groups represented in the parliament. Now that elections are passed it might be interesting to compare the results with the geographical distributions of the tweets.

Migration has always been a constant in human history but how did it change in the last twenty years? Discover the new routes of the migrants on the interactive chord graph “The Global Flow of People” by Nikola Sander, Guy J. Abel and Ramon Bauer.

In some countries getting a university degree might mean falling into debts of thousand of dollars. In this short article on Vox Danielle Kurtzleben underlines the increasing gap between student incomes and debts.

Alberto Cairo has recently accused websites (Vox and 538 among the others) of doing “datum journalism” and not data-journalism. The Niemanlab collected opinions from many different influential experts and academics on Cairo’s point of view.

How many satellites are there in space? Who owns or controls them? What’s their main activity? Skies are populated of these rotating objects since the launch of the Sputnik in 1957. But what happened next? The answer in this data visualization: “A visual history of Satellites”.

“Rating a Healt Law’s Success” is a great piece of data-journalism from the New York Times which shows the existing gap between nations on the number of deaths that could have been prevented with access to health care.

Data Sources

Milena Marin, Project Coordinator at the School of Data, collected, organized a released a list of all the interesting resources that were mentioned or used during the International Journalism Festival. You may find tutorials, readings, slides, videos and much more here.

What’s the beauty of creating data visualizations? Listen to the answer that David McCandless gave to this question at a TED talk conference.

The first week of the European Journalism Centre MOOC “Doing journalism with data” has already gone but Simon Rogers gently published the text of the first part of his module for all of those who might have missed it.

Every once in a while It is always recommendable to update your list of people to follow on Twitter. Travis Korte from the Center for Data Innovation suggests 15 woman data-lovers accounts which it might be useful to monitor.

Another useful list of resources is the one suggested by the managing editor of the International Journalists’ Network Maite Fernandez: if you are looking for guides, articles, videos or data hubs take a look here.

Working with data requires a methodology. If you are a novice you should take a look at this guide from Ictworks.org.

Open data may increase a government efficiency. If you have good idea on how to use data to improve public administration’s services then we suggest you to partecipate to the If Gov Then That initiative.

Manuel Acebedo – Lovely Universe…!!!

Happy week! In our Data Roundup, we everything from Fertility rates data to D3 tutorials.

Tools, Events, Courses

La Naciòn invites the Argentinean data community to celebrate the 10th year of the Maestría en Explotación de Datos by participating to the conference “Hablemos the Big Data”. Program and speakers on www.datamining.dc.uba.ar/difusion.

Researchers at Politecnico di Milano Density Design Lab developed RAW, an online platform built on d3.js library which allows high flexibility in creating beautiful data visualizations.

Data Stories

With the era of Big Data came the era of statistical concepts like causation and correlation. Some say it is not possible to find a single cause for a single phenomenon but multiple correlations which simultaneously influence its occurrence. Sometimes correlations are very curious: take a look at those listed on tylervigen.com.

Fertility rate is a demographic index with important consequences on certain markets. Toy industries, for example, have to monitor it everyday in order to foresee future trends. Paul Hodges states it clearly in its article “Toy industry hit by lack of babies” on the Financial Times Data section.

Federica Cocco, journalist at the Daily Mirror Ampp3d, recently published the story of Boko Haram, the most violent and deadliest among the terrorist groups operating in Africa responsible for one quarter of the violent events occurred in Nigeria in the last 4 years. There are also some great conversations around the use of data tools for complex data stories.

Santiago Ortiz Lifeuniverse is an interactive selection of wonderful information visualizations created by teams or individuals.

The Italian parliament is probably among those with the highest number of old members in the world. Andrea Picchi created an infovis showing the age distribution of parliamentarians since the foundation of the republic in 1946.

Data Sources

Another useful guide from prof. Bradshaw: Coding for journalists: 10 programming concepts it helps to understand.

Are you a D3.js developer in search for tutorials on bubble maps? Maybe you might want to follow these instructions coming directly from the inventor of the JS library: Mr. Mike Bostock.

Rick Harrison – Harvest

Tools, Events, Courses

Spring is the season of data journalism events in Europe, and if you’ve missed the International Journalism Festival in Perugia, you’d better avoid repeating mistakes and register for the Dataharvest+ Conference, which will take place in Brussels this weekend and will gather data specialists and coders from all over the continent.

Visualize is a 96-hour workshop on data journalism and data visualization promoted by the association GliAdditivi. The event will take place in Lecce, Italy, and will last from May 8 to June 18. Special guest: John Grimwade.

Data Stories

Paul Bradshaw on data journalism is always a point of view worth reading. Recently on his Online Journalism Blog, he had fun in comparing the emerging #ddj journalist communities to three different animals according to their different skills: unicorns, racehorses, and mules.

Thomas Piketty’s latest book “Capital in the 21st Century” is surely among the most influential ones in the US. On Quandl.com/PIKETTY it is possible to download and look into the 75 datasets used by the author to conduct his analysis.

Every year, the American NGO Freedom House releases its report on the state of the art of press freedom in the world. Leila Haddou extracted the data and published an article on it on the Guardian Data Blog.

The World Bank is encouraging both countries and private actors to share and spread data at their disposal in order to create new social and economic opportunities. In its last spring meeting “Talking about a Data Revolution”, experts and observers discussed the role that open data may play for countries’ development.

What are the main trends in the cost of living in UK and the US? Which prices increased and which ones diminished since the beginning of the economic crises? The Financial Times posted a short article which offers an interesting perspective on how poverty has changed in the two countries.

Data Sources

Freelancing is a widespread activity among journalists both offline and online. If you are new to this world and you need to know how to measure the value of the article you’ve written or the video interview you’ve conducted, take a minute to read “How do you cost your work as freelance”, again from the Online Journalism Blog.

On the Mu Lin Blog, it is possible to find a list of readings, tutorials, and resources all exclusively focused on data visualization.

The Datavizcatalogue is an ongoing project developed by Severino Ribecca which contains descriptions and details on every possible way to visualize data. I also recommend that you take a look at its suggested readings section.

One of the most promising and positive effects open data may have on societies is that it improves government transparency and helps identify cases of corruption. Europe’s Public Sector Information platform has released a report on this claim which is freely available on its website.

The Knight Center for Journalism will soon launch another great MOOC called “Investigative Journalism for the Digital Age”. The course lasts five weeks and will start on May 12.

Data Stories

The elections for the US senate are about to come, and bets on the winner party have already started. But if you need a much deeper statistical point of view on the event, take a look at “Who Will Win the Senate?” from the New York Times (with interactive graphics made by Mike Bostock).

Sarah Slobin is a data journalist who works as graphic editor at the Wall Street Journal, and she wrote a very interesting article on Source explaining why transforming data into visualizations is not always the right thing to do and why it is important to link the human element to the numbers.

What can we expect from data journalism in the future? What is to come after the launch of FiveThirtyEight and the Upshot? ProPublica’s assistant managing editor Scott Klein analyses the state of the art of DDJ in an interview published on the Tow Center website.

Another interesting perspective on open journalism is that of Simon Rogers, surely among the most heard voices on the web when it comes to data and storytelling. This is his appeal: “Hey Wonk Reporters, Liberate Your Data”.

What role will data visualization play in the climate change debate? Will it help clarifying misunderstandings and promote a better confrontation or will it keep things as they are? Read Megan Albon’s opinion on yaleclimatemediaforum.org.

Internews just concluded the first ever data journalism training event in Afghanistan.

Data Sources

Arthur Charpentier published a long, long, long list of interesting readings, visualizations, and blog posts for data lovers. Scroll it down on “Data News: Why the Boom in Big Data Journalism Makes Sense & More”.

Even though it may seem easy at first, selecting the right colors for your visualization is always a hard task. The guide “UX color theory” is a very useful guide that 5AM Solutions recently published and made available for free to anyone who wishes to know more about colors.

Web scrapers have become the digital version of miners. If you are one of them or if you are just interested in scraping the web, here is a useful introduction from Ken Ross’s blog on how to scrape using Power Query.

Data Stories

The New York Times just introduced to the world The Upshot, its newest experiment in data journalism and data visualization on political and social phenomenon. In its opening manifesto, David Leonhardt clearly stated: “One of our highest priorities will be unearthing data sets — and analyzing existing ones — in ways that illuminate and explain the news.”

We have seen maps about people, natural events, and economic trends, but rarely about music. Movoto provided a solution to this problem by posting an interactive map of the United States, showing the distribution of music genres according to the number of people who listen to them.

In addition to music, Nathan Yau suggests you also take a look at this version of the US territory map which represents the geographical distribution of population density.

Britain is a melting pot of races, cultures, and religions, too. Is this melting pot of people from all over the world changing the predominance of Christianity in England? Gavin Jackson from the Financial Times tried to answer the question in his article “In charts: a Christian country?”.

Youarehere.cc is surely one of the most beautiful geographical visualization experiments ever made so far. It is a website designed by the Social Computing Group at the MIT Media Lab which displays a set of different maps, each specifically created to show a different type of data: bike crashes, coffee shop locations, and much more.

Data Sources

Statsmodel is a Python module used to extract and analyze data. Skipper Seabold published a nice introduction to it in this post on the DC Data Community.

If you are looking for data related to international trade, exports, and imports of goods, then World Integrated Trade Solution site is what you need. The website is a World Bank portal freely available to anyone where is possible to filter your search per country. Siddesh Kaushik from the WB explains how it works here.

ProPublica just announced the release of two JavaScript libraries. The first one is Landline and will help developers turn GeoJSON data into SVG browser-side maps. The second is built on the previous one and is called Stateline and will facilitate the process of creating US choropleth maps.

Data Stories

Chris Michael from the Guardian Data Blog recently published a short article listing the world’s most resilient cities. Michael extracted data from a study of Grosvenor, a London-based company which measured resilience by assigning a value to cities’ vulnerability to environmental changes and their capacity to face political or economical threats.

British citizens might be interested in the quality of air they breathe everyday. Those who are worried about air pollution should take a look at George Arnett’s interactive choropleth map showing the percentage of deaths caused by particulate air pollution in England.

What’s the role of the world tech giants in politics? Tom Hamburger and Matea Gold tried to explain it in this article on the Washington Post by observing the evolution of Google in its lobbying activities at the White House. Google’s political influence increased enormously since 2002 thus making the company the second largest spender in the US on lobbying practices.

Are conservatives all conservatives in the same way, or is there a certain degree of moderation among them and toward different issues? On his newly-born FiveThirtyEight, Nate Silver faces the argument by displaying data on the “partisan split” between the two US parties on several main topics.

If you are Catholic, or maybe just curious, you should be very interested in seeing The Visual Agency’s last infographic, which represents through a series of vertical patterns the number, geographical area, and social level of professions of all Catholic saints.

Gustavo Faileros, ICFJ Knight International Journalism Fellowship, is about to present to the public InfoAmazonia, a new data journalism site which will be monitoring environmental changes in the southern part of South America using both satellite and on-the-ground data.

In addition, as environmental changes increase, so do the number of deaths of environmental and land defenders. The Global Witness team has just published its latest project, Deadly Environment, a 28-page report containing data and important insights on the rise of this phenomenon which is incredibly expanding year by year, especially in South America.

Data Sources

Michael Corey is a news app developer who was involved in the realization process of the National Public Radio mini-site named Borderland. In this post, he analyses the main features of the geographical digital tools that he used to collect and display data on the US-Mexico border which helped him correctly localizing the fences build by the US government all along the line which separates the two Countries.

The data-driven journalism community is expanding rapidly, especially on Twitter. If you need a useful recap of what has been tweeted and retweeted by data lovers, then the Global Investigative Journalism Network #ddj top ten is what you need.
