Visualization purpose is to present some of the main speakers, making particular focus on people: journalists and academics who produce valuable content and who are active (in the web, but non only) relating to mass surveillance topic. To better contextualize their role we have added a small description.
On the left side of the visualization are represented (through circle) speakers that repeats within the body, it is also possible to investigate the information relating to the single person (represented by their photographic image) on the right. In fact for each profile it's made a brief description, it's possible to read the number of articles written, the polarization and finally profile twitter data: followers and tweets number. It is thus possible to realize who is present and active on the web, in the matter of social information as in this case twitter.
The csv created for this visualization contains the names of all the speakers that are repeated more than three times in the corpus and the number of repetitions, the file has been uploaded in Raw to represent data and respective proportions, through the circle packing. The svg file downloaded has then modified, also with photographic images. On the right are repeated photographic images, in connection with name and selected information to describe each speaker.
Some of the important speaker are not only big organizations or information channels (newspaper, news site and others) but also individuals that move personally to defend their opinion about the mass surveillance. First of all, Glenn Greenwald, first to publish the Snowden disclosures, then Jennifer Granick, Director of Civil Liberties for the Center for Internet and Society at Stanford Law School and Civil Liberties Director at the Electronic Frontier Foundation. Both have active twitter profiles through which convey their thoughts. All five are against mass surveillance.
