Caption: Polling data in this illustration and the two that follow are based on a February 2008 Pew Research Center survey. These three illustrations demonstrate software developed at the University of Utah to interactively analyze polling or election data using an animated, doughnut-shaped visualization. Two survey questions are shown in the outer ring of the doughnut: "Opinion of Barack Obama" and "Opinion of John McCain." Underneath each question is a curved bar chart showing percentages of respondents with various opinions of each candidate. (Smallest bars lack labels due to size, but placing a cursor over them reveals their contents in the actual software.) Because the doughnut's central hole is empty, the survey results reflect answers from the entire population of those polled.
