Almost all main chart types support being shown as a small multiples chart. Currently, the exceptions are the charts: Heat Grid, Bullet, Data Tree and Parallel Coordinates.
The multiChart visual role can be bound to any number of dimensions, that are, or will be turned into, discrete.
The multiChart visual role automatically binds to every dimension whose name has the multiChart prefix.
One small chart is generated per unique combination of the values of the bound dimensions that is present in the source data. Each small chart then receives as its data the partition of the source data that shares its unique combination of values.
