Final Fantasy X – Skill sphere grid
The Sphere Grid is the ability and character development system in Final Fantasy X. It is a roughly circular grid of interconnected nodes arranged in smaller circular clusters, containing all the abilities and special skills the player characters can learn. The name of the system is used both to refer to the grid’s design, and to the use of spheres to activate the nodes. (finalfantasywikia)
