A funny thing happened during this summer's health care debate: a chart that purported to show the organizational structure of the Democratic health care reform proposal took over the media cycle and triggered a partisan visualization volley. Since then, the original chart has frequently been used as a provocative protest sign and is now the subject of a congressional investigation. What was it that made this data visualization so powerful and politically potent? How can your organization or your cause harness data visualization as a messaging medium? With these health care chart wars as a backdrop, this presentation will show you how to be a smart consumer of data visualizations and infographics.
