{{Uses Wikidata|P1087}}

This template uses [[Template:WikidataChart]] to create a [[line chart]] of the [[Elo rating system|Elo ratings]] of chess players. Data sources are [https://ratings.fide.com/download.phtml FIDE] (period since 2001) and [http://www.olimpbase.org/Elo/ OlimpBase] (period 1971 to 2001). The Elo numbers were added to the Wikidata items of the chess players, so any errors or missing Elo numbers must be corrected or supplemented on Wikidata.
