This week we were joined by Fogocruzado founder and journalist Cecília Olliveira.

Cecília launched Fogocruzado after working on a story and discovering that data on armed violence in Rio and elsewhere in Brazil, something she was seeking at the time for the investigation, was not being robustly collected. She came in to our Server to discuss the power of data and why plotting data that hasn’t before been collated can illuminate otherwise hidden trends and be vital when it comes to informing the public of what is going on in their own cities.

This talk was hosted by Charlotte Maher on Thursday the 19th of June 2025. Music featured is courtesy of Artlist.
