Data-driven styling for boundaries lets you access Google's polygons for
administrative boundaries, apply styling to boundary polygons,
and display them on your maps.
Data-driven styling for boundaries lets you target regions by place ID and apply
custom styling to boundary polygons on the map. Each feature type represents a
type of region; you select which feature types to enable when configuring a map style.

Feature types
Data-driven styling provides access to Google boundaries for feature types that
represent administrative areas. Administrative areas are categorized by
function, for example country, state, locality, and postal code. Feature types
are arranged by administrative level, the structure of which varies by country.
The following feature types are supported for data-driven styling for boundaries:
COUNTRY — The national political entity, typically the highest order
type.ADMINISTRATIVE_AREA_LEVEL_1 — A first-order civil entity below the
country level. Within the United States, these administrative levels are
states.ADMINISTRATIVE_AREA_LEVEL_2 — A second-order civil entity below the
country level. Within the United States, these administrative levels are
counties.LOCALITY — An incorporated city or town political entity.POSTAL_CODE — A postal code, as used to address postal mail within
the country.SCHOOL_DISTRICT — A school district; includes unified, elementary,
and secondary.
Administrative areas are represented on the map as feature layers; each type
has its own layer. Feature layers are enabled per map style. You can choose
which feature layers to enable when setting up your map style in the Google Cloud console.
Style boundary polygons
You can apply styles to boundary polygons for fill (color, opacity), and stroke
(color, opacity, stroke weight). Use styling to:
