Olympic Medals Cartogram
The size of each country’s circle represents how many medals they were awarded for that particular year. Scroll back through each summer games to see how countries fared over time. Click the “by ranking” tab to sort the countries into a list.
The graphic was created using a force-directed graph using a particle system. Countries try to locate themselves near where they are geographically located as well as close to geographically neighboring countries. The circles do not overlap. Flash is a bit too slow to be interactive, so there is a pre-render on our side to determine how each year’s layout will appear.
