What’s the global data journalism community tweeting about this week? Our NodeXL #ddj mapping from April 15 to 21 finds an informative interactive tool about health by generation by @srfdata, a piece by academic @wsaqaf on how journalism can utilize blockchain for investigations, data visualization teaching materials by @R_Graph_Gallery, and a book draft on data feminism by @kanarinka and @laurenfklein.
How Healthy Is Your Generation?
Inspired by Vox’s “Today’s Teens” story, SRF Data created an interactive tool using health survey data from Switzerland’s Federal Statistical Office. Select your age and gender and the tool will tell you the biggest health problems among those in your age group (with bonus cute gifs!).

Blockchain and Journalism
What can blockchain offer investigative and data journalists? Former journalist turned academic Walid Al-Saqaf argues that all kinds of stories could benefit from using blockchain as a data resource and offers two examples.
In this interview by @datajournalism I argue that #blockchain could be of value for data journalists, #journalism and media at large: https://t.co/fadYiUdTY2 I also plan to talk about that at next week's #StockholmBlockchainForum https://t.co/WyQRHJrXUB

Catherine D’Ignazio and Lauren Klein penned a book on data feminism that goes beyond gender, because they believe the term encapsulates much more than that. As they state in the book’s intro: “Data Feminism is a book about power in data science. Because feminism, ultimately, is about power too. It is about who has power and who doesn’t, about the consequences of those power differentials, and how those power differentials can be challenged and changed.”

Tracking Train Timings
Both Germany and France have invested billions in their inter-city high-speed train networks, ICE and TGV, respectively. But as it turns out, the trains run faster on French tracks. Der Spiegel compares the two services and dissects the reasons why German trains are traveling at a slower pace.
Germany and France followed different approaches for their high-speed rail services. France built a separate network with few stops and fast connections. @hdambeck simulated travel times if Germany had followed the same approach (article in German):https://t.co/TJ1bLSDRbw #ddj pic.twitter.com/hSXzuZLnf6

Biking in London Data
Using the Freedom of Information Act, freelance journalist James O’Malley requested hiring data for London’s Cycle Hire bikes. He mapped out all the available bike stands and using red and green pins, he indicated which stands had more hires than docks, and vice versa.
NEW NERDY STUFF! I obtained a cool little dataset of London Cycle Hire usage split out into the number of dockings and the number of hires from a given location – revealing a hidden geography of sorts to how Londoners move around.https://t.co/blIEgOwArt pic.twitter.com/g0cuPtXjEK
