GIJN’s Data Journalism Top 10: Ring of Fire, Political Dynasties, Data Janitors, Hong Kong Protests

What’s the global data journalism community tweeting about this week? Our NodeXL #ddj mapping from June 10 to 16 finds a gorgeous series of data visualizations by National Geographic on the Pacific’s Ring of Fire, Bloomberg analyzing the influence of dynasties in Philippine politics, RStudio‘s Hadley Wickham talking about why you shouldn’t assign data cleaning to a “data janitor,” and BR Recherche looking at the complexity of privacy policies.

Ring of Fire

Here are some gorgeous data visualizations and analysis by National Geographic on the Pacific’s Ring of Fire — a 40,000 km volcanic belt stretching from New Zealand to the tip of South America with potential to disrupt hundreds of millions of lives in 40 countries.

Dynasties in the Philippines

The Philippines’ politics has long been dominated by dynasties: the Aquinos, Osmeñas and Marcoses. Bloomberg takes a closer look at the nation’s influential families and visualizes their power and positions over the years.

The Problem of Having a “Data Janitor”

Have you ever heard of a bear obstructing data collection? Read this interview with RStudio’s chief scientist Hadley Wichkam. He talks to ProPublica’s Hannah Fresques about how to find stories in commonplace data, the problem of having “data janitors,” the need for symbiosis between those who use R and those who use Python in the newsroom, and more.

Do You Read Privacy Policies?

Inspired by a BBC article, BR Recherche and BR Data used a text analysis tool developed by two scientists at Germany’s Universität Regensburg to analyze the privacy policies of several platforms, including Twitter, Facebook and Instagram. They discovered that the policies were far too complex for users to understand and required far too long a time to read. The New York Times also came to a similar conclusion here. (In German.)

Fun Infographics for Kids

Here’s a fun way for children to learn about data visualization. In “Yo y El Mundo” (Me and the World), authors Mireia Trius and Joana Casals present a colorful collection of infographics on a wide range of topics, from breakfasts in different countries to cities with the worst traffic. Although the book is in Spanish, data viz expert Alberto Cairo recommends it to all.

Hong Kong Protests

The Financial Times uses Google Earth Studio to visualize the progression of the recent Hong Kong protests against a controversial extradition bill. The bill, which was suspended indefinitely on June 15, would have allowed the extradition of suspects from Hong Kong to face trial in mainland China.

Fundamentals of Data Visualization

The book “Fundamentals of Data Visualization” by integrative biology professor Claus O. Wilke will teach you the basics, including visualizing amounts, distributions, proportions, trends, geospatial data, and more. The book’s source code is hosted on GitHub. Data Journalism Turkey profiles the book here.

Female Representation in Art Museums

“When you ask the audience what art they want to see, we often hear the names of well-known male artists,” says Björn Quellenberg, Kunsthaus Zürich art museum’s spokesperson. and Radio Télévision Suisse analyzed exhibitions held from 2008 to 2018 in 80 art museums and galleries in Switzerland and found that only a quarter of the solo exhibitions were works by women. (In German.)

Daycare Deficiency

Neue Osnabrücker Zeitung’s research suggests that the German government’s provision of childcare has sorely underestimated the country’s needs for daycare services catering to toddlers under three years old. Data on Github. (In German.)

Data Visualization Critique

“In many cases, it’s not necessarily what you say, but how you say it.” Economist Jonathan Schwabish shares his thoughts on how polite we need to be in critiquing others’ data visualizations.
