893 airports from Natural Earth: circles by type, marks with IATA labels, tooltips and popups.
Every airport is a circle coloured by its type field (categorical classification). Hover a point for a tooltip, click it for the popup with all fields.
A second layer draws major airports as a Spatly mark with the IATA code as a label. The circle layer fades to 50 % on this beat, using per-beat layer opacity.
This beat highlights Istanbul Airport (IST) with a pulsing ring and a tilted camera. Highlights are per-beat expressions on a layer.
