This is a pie chart, which, outside of the bar graph, might be the simplest and most recognizable type of visual data representation in existence. Pie charts were part of a movement away from spreadsheet-style data presentation, and the forerunners of the diverse methods of visual representation we have studied in this course. As this specific chart shows, one of the great benefits of a pie chart is in how they simply data into a fairly universally understandable image. Pie charts and their ilk are excellent tools for presenting information to viewers that would be unable to understand facts and figures on paper, and also for making plain data have a stronger impact on its viewer.
