Visualizing Density of Healthcare Workers Across Time and Countries

We present a visualization that makes use of a novel highlighting and animation technique. The primary motivation behind the design of this visualization was to enable people to look at data about healthcare services, and specifically to increase their knowledge about the impact of the amount of healthcare workers per capita. We use animation in the process of showing changes within an individual country over the course of several years, as well as to facilitate comparisons between multiple countries at once, by letting people keep track of selected countries. We discuss the motivation behind our use of animation, our choice to include a search bar, and potential areas for improvement and revision.
