And what is that data journalism?

The data journalism (or data journalism, in English) is a journalistic practice that seeks to harness the enormous amount of data available in a multitude of sources, preferably digital (and the web is the first, but not the only) to tell news stories. Many of these data and the relationships established between them, can explain increasingly complex phenomena in a relatively simple manner. Even more ideally, allow sharing not only their own news or reports obtained through them, but also help recipients can review the data themselves and draw further conclusions.
