Data journalism, simply put, is journalism using data - journalism about data, and journalism that draws on data. Data can assist to tell a complex story with infographics that illustrate and interpret the wealth of digital data now available.

The European Journalism Centre and the Open Knowledge Foundation have produced The Data Journalism Handbook. The Handbook is an ebook, freely available online under a Creative Commons Attribution-ShareAlike license.

It introduces data journalism and provides case studies; discusses finding and understanding data; and explains how to deliver data, suggesting useful tools for visualising complex data. The Data Journalism Handbook is a great example of collaboration that encourages open access and the use of freely available research data.

For great examples of Data Journalism, visit The Guardian's Datablog or Information is Beautiful. Data Driven Journalism.net is a useful site to investigate as well, providing a video to explain the concept of data journalism further.
