GIJN’s Data Journalism Top 10: Visualizing Air Raids, Dictator Decrees, Dataviz Crimes, Random Samples

What’s the global data journalism community tweeting about this week? Our NodeXL #ddj mapping from March 25 to 31 finds @ajlabs visualizing air raids through sound, @infobae exposing secret dictatorship decrees in Argentina, @albertocairo presenting on how charts can mislead (and how to fix them), and @TheEconomist laying bare “crimes” against data visualization they have committed.

Visualizing Air Raids Through Sound

The AJ Labs team walks us through their process of visualizing 19,000 air raids carried out by the Saudi coalition in Yemen since 2015. They explain why they resisted using a traditional map with circles showing the location of the raids and opted instead for an audio visualization.

Secret Dictatorship Decrees Analyzed

The Infobae data unit downloaded and reviewed more than 7,000 secret decrees signed by the last Argentine military dictatorship between 1976 and 1983. The declassified decrees had never been processed and analyzed in their entirety until now.

How Charts Lie

At the 27th Infographics World Summit, data viz expert Alberto Cairo presented his thoughts on how infographics can be misleading due to a variety of factors, such as graphical illiteracy, confirmation bias, fear of complexity, uncertainty and inaccurate descriptions. Get Cairo’s book on the topic here.

Crimes Against Data Visualization

Getting data visualization right isn’t easy, and even the experts get it wrong sometimes. The Economist’s Sarah Leo writes a refreshingly honest and revealing post on the mistakes the organization has made in producing visualizations.

Can AI Break the Next Panama Papers?

Three years ago, 400 journalists used open source data mining technology and graph databases to wrestle with 11.5 million documents and expose offshore finance secrets now known as the Panama Papers. In hindsight, Marina Walker Guevara, deputy director of the International Consortium of Investigative Journalists, wonders what stories they might have missed and how artificial intelligence could possibly help to uncover more money laundering in the future.

Random Sampling Explained

How can a survey of a small group of people measure the public opinion of a whole country? This neat explainer by Pew Research Center (published in 2017, but relevant as ever) breaks down how random sampling works and how the data collected can be weighted and adjusted to match the general population.

From Pulp Fiction to Rock Bands in Rio

Multidisciplinary designer Carol Cavaleiro has been designing infographics for the past seven years and has worked for Estadão, UOL, Metro and O Globo. Her portfolio is a glorious, colorful visual feast, and includes visualizations about Pulp Fiction, dogs matching Volkswagen cars and rock bands in Rio.

Football Finances

Kieran Maguire, a lecturer in football finance analysis at the University of Liverpool, assesses how three English football clubs ended up struggling financially. One of the key factors he outlined is the lack of control of player costs in terms of both wages and transfer fees.

Final Call: Submit Your Data Projects

April 7 is the deadline to submit your brilliant data journalism project for the Data Journalism Awards. Stand a chance to win an all-expenses-covered trip to Athens, Greece, to attend the GEN Summit and Data Journalism Awards 2019 ceremony, taking place from June 13 to 15.

UK Data Journalism

Top UK data journalists will gather on May 3 to share tips on producing cutting-edge reporting and finding stories in structured information. Speakers include the BBC Shared Data Unit’s Pete Sherlock, The Times’ Leila Haddou and The Guardian’s Caelainn Barr.
