This page displays rankings from the International Chess Federation for the past year.
A single JavaScript data loader, top-ranked-players.json.js, accesses the data (in a Zip archive) from the site above, performs some basic wrangling, and writes the simplified snapshot of rankings in JSON format to standard out.
Bump charts are made with Observable Plot, and highlight changes in ratings for the top Women’s and Men’s chess players over time.
