-Color channels (**fill** and **stroke**) are bound to the *color* scale by default, unless the provided values are all valid CSS color strings or nullish, in which case the values are interpreted literally and unscaled. Likewise, if the dot mark’s **symbol** channel values are all symbols, symbol names, or nullish, values are interpreted literally and unscaled; otherwise, the channel is bound to the *symbol* scale. (In the case where some color and scale channels are literal values, which other color channels are not, the channels with literal values will now automatically opt-out of the corresponding scale. This deviates from the previous behavior, where *all* channels associated with a scale were required to be literal values in order to have the scale default to an *identity* scale.)

 The mark **facet** option can now be set to *empty* such that a mark is only rendered on empty facets. This is typically used in conjunction with decoration marks, such as diagonal labels in a scatterplot matrix.
