Data visualizations, frequently referred to as information graphics, are a powerful tool that will inform and educate your readers. Often important data-heavy information can bog down a narrative or slow the pacing of a story. That data might be edited out to streamline a story or put into a table for readers to browse. A better solution is to use simple graphics that can be created in minutes and delivered for free using web tools. These information graphics will compliment and add context to your stories. Graphics can help you highlight important information from a database in a way much easier to understand than a text-only presentation. – Data Visulations: Basics by Len DeGroot
Or for example, what if you wanted to show the location of every Tweet ever posted, billions of them. It might look something like this.
Places to start exploring:
Tableau Public, a free data visualization software, has a nice infomercial that explains the basic process.
Visual.ly is great place for exploring, creating, and sharing infographics. And it’s a hub to connect designers with clients.
FlowingData explores how designers, statisticians, and computer scientists are using data and visualization.
VisualJournalism – A blog on information graphics and journalism by Gert K. Nielsen.
Data Journalism Handbook – This open-source book is a collaboration of 50 journalists and programmers and offers data journalism case studies from news organizations like The New York Times, Financial Times, Guardian, and Chicago Tribune.
Skills for Data Journalism:
Data journalism can be done by one individual or by a team of people. The main tasks can include:
1. Reporting – the ability to obtain data and identify a compelling story within a mass of information.
2. Expertise with data and research – the ability to mine, organize, and clean data.
3. Web development and design – the ability to create a web-based visualization that presents the data in an understandable manner and allows the user to navigate it.
Four Simple Infographics You Can Create:
1. A word cloud is a visual representation for text data that seeks to demonstrate how words are used.
For example: Here is a wordcloud of the most common words used in each presidential inaugural address from Washington to Obama.

2. Graphs and Charts
USAToday is famous for their simple charts and graphs.

3. Interactive map mashups have become a standard way to tell a geographic story on the web. A mashup is an application that combines data from more than one source into a single integrated tool.
Google Maps allows you to clickable maps and embedded them in your blog.
4. A timeline can be a great way to tell a story that stretches over a long period of time. It can also be used to chronicle the life of a person or institution.
You can use timetoast to create a simple online timeline.
