Default view starts at the player's first available FIDE rating. Rating lines use period-to-period steps, and each FIDE rating period is plotted as one point. Peak ratings only consider FIDE rating-list periods available from 2013 onward. National ratings are shown as current snapshots because historical national lists are not available.
