open data day

What’s the global data journalism community tweeting about this week? Our NodeXL #ddj mapping from April 2 to 8 finds an alarming piece by @iamdylancurran on how much data Facebook and Google have actually gleaned from us, @OCCRP’s powerful database of public records and leaks, @davidottewell’s take on the evolution of data journalism and an investigation by @TheInterceptBr into the militias in Rio de Janeiro.
