Hi everyone!
I would like to share a story by Stuart A. Thompson and Charlie Warzel about an investigative look into mobile tracking in the US.
LINK: https://www.nytimes.com/interactive/2019/12/19/opinion/location-tracking-cell-phone.html
The reporters used a massive data set consisting of billions of rows that logged phone pings with a geometric data. They then used this data to tell an exciting story about how tracking works, how "easily" it can be done and that it is almost impossible to avoid (apart not having any electronic device on you). I appreciate the different interpretations of the same data and how it can be used to track and identify even a specific person, given that you have enough information on them. Also, the visualizations are simple but very useful, in my opinion - conveying the message well while directly showing what the journalists want you to see.
Cheers,
Andrew
