Today more data is being gathered and stored than ever before. This provides journalists with a veritable font of information that is not always easy to find. The agency for data journalism OpenDataCity gives the media a key for using this open source material: with the help of visualisations the start-up provides access to complex subjects. An example: an interactive map makes links between politicians and lobbyists visual. All applications are freely accessible and conceived by a team of developers, graphic designers, and journalists. Together they provide for more openness in the data jungle and promote new thinking in the media.
