Data journalism includes six main Areas covered such as Computer assisted reporting, Infographics, Data visualization, Interactive visualization, Database journalism.
For example, Computer-assisted reporting is that journalists and other people gather and analyze the information to editor news through computers. Infographics are that complex knowledge, information and data are presented through graphic visual, this method is beneficial to understand information by readers more easily.
Data can be the resource for data journalism. An example is Las Vegas Sun’s 2010 Do No Harm series on hospital care. Journalists analysed 2.9 million records and 3600 cases in hospital to provide clear data for readers. It obtained a real impact which is six pieces of legislation by Nevada legislature.
Data also can be the tool to find a story.
