A different visual approach to associate likelihood of occurrence of a given event to the lived experience of people viewing the graph. A new interface developed by Giorgio Comai (OBC Transeuropa) for EDJNet

In their 2007 book “The illusion of certainty: Health Benefits and Risks”, authors Erik Rifkin and Edward Bouwer addressed a number of aspects related to the communication of risk to individuals and broad audiences, arguing that adequate communication of risk, including on the uncertainty embedded in risk assessments, is fundamental to personal and collective deliberations.

The book presents a number of interesting concepts (I suggest reading the…


What does Wikidata know about members of the European Parliament? Let’s find out using our new R package tidywikidatar. A post by Giorgio Comai (OBC Transeuropa)

An article by Monika Sengul-Jones titled “The promise of Wikidata” published on datajournalism.com a couple of months ago highlighted how Wikidata — a sort of database associated with Wikipedia — could be used by data journalists in a number of ways. …


A detailed account of the steps, choices, and methods that led to EDJNet’s investigation on the availability of psychological treatment in the public healthcare systems in Europe. The investigation was run by Civio and it was published in March 2021.

The investigation began in May 2019 and has lasted for many months. It was carried out by Ángela Bernardo and María Álvarez del Vayo (reporting and data); Carmen Torrecillas and Antonio Hernández (data visualization); Eva Belmonte (coordination and editing); Miguel Ángel Gavilanes and David Cabo (data); Olalla Tuñas (interviews); Aspasia Daskalopoulou, Monica Georgescu, and Lucas Laursen contributed to this work.

The sources

We started the investigation by soaking up the subject: we interviewed experts and read reports, papers and previous research on the subject. We discovered that there was no data on the reality of access to mental health, and that the…


Daniela Späth, Eva Lopez, Andy Giefer from Deutsche Welle (DW) present their first experience with AR and Instagram Face Filters — an innovative form of interactive journalism, conducive to highly shareable content.

If you are into data-driven journalism, you have probably come across the NYT’s You Draw It series, where users have to draw the second half of a graph and thus interact with a data story. We have always liked this idea. And we thought that by adding augmented reality (AR) and Instagram face filters, we could develop it further. Our aim: Creating a new worthwhile form of interactive…


How might we best tell data-driven stories on social media? A guest post by Eva Lopez, from the data team at Deutsche Welle.

For a long time, social media was merely an afterthought in the daily routine of data journalists. Why worry about promoting a story and making it more accessible when you can scrape websites and build sophisticated charts all day? A project launched by the European Data Journalism Network has been working on changing that status and mindset. DW Data is a part of the initiative, and our Eva Lopez — a data journalist and innovation manager — frequently shares what she and her team have learned. These are the latest insights. The post was originally published on DW Innovation blog.


This post presents a data exploration tool developed by Giorgio Comai (OBC Transeuropa) for EDJNet. If you have a spreadsheet with longitude and latitude columns and would like to have a look at those data on a map or associate them with administrative units across Europe, you may find this tool useful.

You can try the tool online, or check out this screencast for an overview of its main features. The interface is available also through the R package latlon2map.

Scientists across different disciplines are increasingly taking up the nice habit of publishing the datasets that emerge from their research, and these often include geolocated data. The same is true with open data distributed by public administrations: more and more, such datasets include geocoded information.

All of this sounds like a great starting point for data journalists. If the data is available for a large area, for example, it will surely take…


This post by Giorgio Comai (OBC Transeuropa) describes a workflow and some points of reference for anyone tempted by the idea of using Google Earth for data visualisation.

Google Earth Studio is a fancy tool that allows for the creation of videos of stunning quality, by making it possible to create smooth transitions between locations across the globe, zooming in closer to the ground, and showing mountains and cities in 3D.

Here is their own promo video:

However, so far I have not really seen it used for data visualisation, nor I have seen any post online discussing how to use Google Earth Studio with data. So… I decided to give it a try, and report back.

In this post, I will describe how I made this…


In this video, Giorgio Comai (OBC Transeuropa) points at some of the issues that characterise data grids and that may generate misunderstandings. He mentions how gridded data can be generated via satellite imagery and machine learning techniques .

A new straightforward online interface that makes it easy to create and customise decent-looking charts for grant applications

by Giorgio Comai (OBC Transeuropa)

The prequel

Among the many things that the Covid-19 brought to journalism, there is one that is both a boon and a bane: grants. As the pandemic brought new challenges to the sustainability of many media organisations, a number of initiatives and donors stepped up to provide financial assistance to media organisations and journalists. In many cases, the application process was mercifully straightforward, also due to the urgency of the matter: a brief form was all that was needed to apply to some of these funding lines. However, it is easy to predict that such mercy will…
