“In 1995, none of the states has an obese population greater than 21%. By 2011, the leanest state, Colorado, has an obesity rate of slightly greater than 21%.” A disturbing statistic this infographic shares. Popsci shared this interactive infographic that allows you to watch the obesity rate in the US increase over time using pie charts.
More relavent to this blog, this is a great example of how to share this type of information. Through a combination of pie charts, pie chart sizes, and a modified bar chart allows you to view the information as the timeline passes. When creating infographics with your students, consider using multiple types of charts like this infographic does.
