Transforming data access through public visualization

ABSTRACT

Data visualization has historically been accessible only to the elite in academia, business, and government. It was "serious" technology, created by experts for experts. In recent years, however, web-based visualizations--ranging from political art projects to news stories--have reached audiences of millions. Meanwhile, new initiatives in government, aimed at all citizens, point to an era of increased transparency.

What will this new era of data transparency look like--and what are the implications for technologists who work with data? To help answer this question, we report on recent research into public data analysis and visualization. Many of our results come from Many Eyes, a "living laboratory" web site where people may upload their own data, create interactive visualizations, and carry on conversations. Political discussions, citizen activism, religious discussions, game playing, and educational exchanges all happen on the site. To further support these scenarios, and the users they represent, will require continued innovation in data presentation and interaction.
