DATA VISUALIZATION Time to tell a story with data, and make it much more visual.
What is the database? It helps to reduce information into small pieces and then allows users to relate those pieces back to each other in a dynamic and flexible way. Journalists acquire data in 4 primary ways:

Via submissions from site visitors who fill out Web form (example: www.GasBuddy.com)
By using the unstructured text of a Web page or other digital documents
