Many organizations use infographics to present arguments. Here, the Centers for Disease Control compares fast-food portion sizes from the 1950s and today to make the case that, as the text at the top states, “Portion sizes have been growing. So have we.” The text goes on to suggest steps people can take to reduce their portion sizes.

Several sites on the web, such as infogr.am, offer free templates for making infographics.
