The same technique is applied in the other dimensions presented: medals by geopolitical groups (China, EU, ex soviet republics) , by sport (swimming, athletics, gymnastics) , by GDP and by population. It also contains full information of the final medal count by country and a day-by-day gold medal count (annotated bar char in the lower half). All parts of the visualisation are commented to give an overall picture of the event.
