Ingredient Atlas
Every ingredient in US dog food, mapped by how it's actually used — each one's position learned from 1,285 real product panels across 411 brands.
PositionWhere an ingredient sits is set by what it's used with — its companions across every recipe. Two ingredients land close when they do the same job, so distance reads as substitutability.
ColorColor shows what an ingredient is — its role (protein, grain, oil…), or switch to cluster for groups that recur together.
