Exploring The Types Of Messages That Pie Charts Convey In Popular Media

In popular media, information graphics (pie charts, bar charts, line graphs) are frequently used to convey high-level intended messages. This paper focuses on the pie chart graphic type. We have collected a corpus of pie chart information graphics found in popular media, and for each chart, a team of annotators recognized its intended message. In this paper, we report on the types of intended messages that the team of annotators recognized and their inter-annotator agreement. We also briefly survey some of the communicative signals that graphic designers used which helped the annotators recognize these messages.
