It feels wrong to me to view it this way. The first column of a table should be the item, and the remaining columns should be the details of the item. This implies 77 total medals is the item, and the detail of that is the US. It just parses wrong in my head.
I almost wonder if the proper order isn't some sort of % of medals won vs participants for each country, so countries that have few athletes in the competition but all medal in most of the events they're in show highly.
Then again, I'm willing to admit I have no clue what people that look at these charts are after.
