This map ranks countries worldwide based on the
performance of their chess players across various categories.

First, the official leaderboards are retrieved from the Chess.com API.
Next, the individual player scores are aggregated to calculate each
country's total score.

A country's rank is then determined based on this total score.

The total score represents the sum of all individual player scores from
a given country. Larger countries have an advantage due to
their higher populations. To create a more balanced ranking, population data
is retrieved from The World Bank API and applied to the following formula:

Total score / population * 1000 = average score.

The brighter the color, the higher a country's rank on the chess leaderboard.
Simple as that!
