CGTN visualized all the gold medals awarded to athletes at past Summer Olympics.

Note: Only medals in sports that are still on the current Olympic program were tallied.

CGTN对历届夏季奥运会颁发过的金牌和获得相应金牌的国家和地区进行了数据可视化分析，通过大数据揭开夏奥夺金的秘密。

注：该数据仅统计现有的奥运竞赛项目。

This graphic maps all Olympic sports according to the number of gold medals given out and the number of countries and regions that have won gold.

With most dots tightly clustered around the best fit line, it suggests gold medals have been consistently distributed among countries across most disciplines.

在该交互图中，绝大多数圆点紧密地聚集在拟合线周围。这表明，金牌数量与夺金国家和地区数量之间总体呈正相关关系，即颁发的金牌越多，相应的夺金国家和地区就越多。

A couple of dots clearly above the line – indicating sports where medals have gone to a higher than average number of countries and regions – show that some Olympic disciplines, including football, taekwondo and triathlon, have thrived on their unpredictability.

而一些圆点则明显位于拟合线上方。这意味着，项目充满着极大的不确定性，足球、跆拳道和铁人三项等皆是如此。

All of this leads to a compelling question as sports fans prepare to watch the world's finest athletes dazzle in the Japanese capital: Which countries or regions will flex their muscles in what Olympic sport?

当全球各地的顶尖运动员在日本东京齐聚一堂，准备向奥运殿堂的最高荣誉发起冲击之时，一个重要的问题呼之欲出：究竟哪些参赛国家或地区在哪些项目上一骑绝尘呢？

众所周知，在奥运会的众多项目中，个别项目有绝对优势力量的存在。

While China is the undisputed champion in table tennis, racking up 28 of the 32 golds on offer, the U.S. has topped the rest of the world in basketball. Of the 30 possible golds in the event, the U.S. has won all but seven.

中国是无可争议的乒乓球“霸主”。自1988年乒乓球被列入奥运项目以来，中国队已囊括32枚金牌中的28枚。 美国则是在篮球独步天下，在该项目产生的30枚金牌中，仅有7枚金牌“逃出”了美国的手掌心。

China has enjoyed similar superiority in badminton, with 18 out of 34 golds going to Chinese shuttlers.

It's worth noting that China is the only country ever to complete a clean sweep of medals in that sport at the Olympics, with its players powering to gold in all five events at London 2012.

中国在羽毛球项目的优势同样明显。在已产生的34枚羽毛球金牌中，有18枚被中国选手收入囊中。

尤为值得一提的是，中国曾在2012年伦敦奥运会包揽了羽毛球全部5个项目的金牌。这一成就至今仍无人企及。

But there's no guarantee that Olympic dominance will last forever, and some events have witnessed a stunning shift in power in recent decades.

有趣的是，奥运“霸主”在赛场上的优势地位并非牢不可破。一些项目经过数十年的发展，领头羊的国别亦有惊人的变化。

Diving had been the domain of the U.S. for a long time, and nobody could stop the Americans from coming up on top in the Olympics until 1984, when China made its presence felt in Los Angeles.

Since then, Chinese divers have had a scintillating run of form that has seen them topple their U.S. rivals.

美国曾在奥运跳水项目中战无不胜、所向披靡。直到1984年洛杉矶奥运会， 中国才得以厚积薄发、崭露头角。

此后，中国便开启“逆袭”模式，使跳水成为中国的优势项目。

Fencing has traditionally had a strong association with three European leviathans.

Italy, France and Hungary account for more than half of the fencing golds awarded in Olympic history. But Russia has been a nation on the rise in the sport, winning medals at every Olympic Games since 1992.

击剑一直是欧洲三大巨头的传统优势项目， 意大利、 法国和 匈牙利收获了该项目半数以上的奥运金牌。

此外， 俄罗斯逐渐成为一支不容小觑的力量，在1992年后的每届奥运会上都有奖牌收获。
