Swedish students scored poorly on a pre-test about global health and development issues. The document argues this was due to preconceived ideas rather than ignorance. It presents animated data visualizations showing trends over time in life expectancy, family size, income distribution, and child mortality across different regions of the world. The visualizations illustrate how countries like China, Latin America, and Africa have changed, with China focusing on better health and Latin America moving towards smaller families. It concludes that such data is not being used efficiently and that animations, interactivity, and search functions are needed to better present information about global trends.
