Attribute values that make this variant one variant of its product, as a map of attribute name to value, e.g. {"size": "Large", "color": "Blue"}. Names are normalized to snake_case identifiers (Ring Size becomes ring_size) and come back in alphabetical order. Every variant on a product must carry the same attribute names and a distinct set of values. Send null to make the variant an ordinary pricing option again.
