Une carte web en cluster regroupe automatiquement les points proches les uns des autres en grappes visuelles. Chaque grappe affiche le nombre de points qu'elle contient. Lorsque l'utilisateur zoome sur la carte, ces grappes se divisent progressivement en groupes plus petits, jusqu'à révéler les marqueurs individuels.

Ce type de carte est assez simple à mettre en place avec Leaflet et c'est un bon moyen pour gagner en lisibilité.
