Data Visualization in Government

Jul 2, 2013

The report by Genie Stowers for The IBM Center for The Business of Government:

“The purpose of this report is to help public sector managers understand one of the more important areas of data analysis today—data visualization. Data visualizations are more sophisticated, fuller graphic designs than the traditional spreadsheet charts, usually with more than two variables and, typically, incorporating interactive features. Data are here to stay, growing exponentially, and data analysis is taking off, pushed forward as a result of the convergence of:

• New technologies
• Open data and big data movements
• The drive to more effectively engage citizens
• The creation and distribution of more and more data…

This report contains numerous examples of visualizations that include geographical and health data, or population and time data, or financial data represented in both absolute and relative terms—and each communicates more than simply the data that underpin it.In addition to these many examples of visualizations, the report discusses the history of this technique, and describes tools that can be used to create visualizations from many different kinds of data sets. Government managers can use these tools—including Many Eyes, Tableau, and HighCharts—to create their own visualizations from their agency’s data.

The report presents case studies on how visualization techniques are now being used by two local governments, one state government,and three federal government agencies. Each case study discusses the audience for visualization. Understanding audience is important, as government organizations provide useful visualizations to different audiences, including the media, political oversight organizations, constituents, and internal program teams.To assist in effectively communicating to these audiences, the report details attributes of meaningful visualizations: relevance,meaning, beauty, ease of use, legibility, truthfulness, accuracy,and consistency among them.”
