Ética Segura network. Ética Segura deals with ethical issues in journalism— written and visual— and it's related to the Gabriel García Márquez Foundation for Ibero American New Journalism.
The interview, on the ethics of infographics, data, and visualization, was conducted in Spanish. If you don't understand that language, I guess that you could try to run the transcription through Google Translate. If you scroll down to the bottom of the interview you will also find some video lectures that I've used in all my MOOCs. Those are in (thickly accented) English.
