A facet is a trellis plot (or small multiple) of a series of similar plots that displays different subsets of the same data, facilitating comparison across subsets.

The facet channels (facet, row, and column) are encoding channels that serves as macros for a facet specification. Vega-Lite automatically translates this shortcut to use the facet operator.

To superimpose one chart on top of another.

Vega-Lite specifications are JSON objects that describe a diverse range of interactive visualizations. Besides using a single view specification as a standalone visualization, Vega-Lite also provides operators for composing multiple view specifications into a layered or multi-view specification. These operators include layer, facet, concat, and repeat.

Single view specification, which describes a view that uses a single mark type to visualize the data.

All view composition specifications (layer, facet, concat, and repeat) can have the resolve property for scale, axes, and legend resolution.

Vega-Lite determines whether scale domains should be unioned. If the scale domain is unioned, axes and legends can be merged. Otherwise, they have to be independent.

There are two options to resolve a scale, axis, or legend: "shared" and "independent". Independent scales imply independent axes and legends.

all view layout composition (facet, concat, and repeat) can have the following layout properties: align, bounds, center, spacing.
