Define the style and display a polygon for a specific administrative
boundary that you choose, to highlight an area that is important to
your users. The region lookup utility makes it easy for you to use
Place IDs at no cost to find the Google administrative boundaries
you want. You can customize fill and stroke color, fill and stroke
opacity, and stroke weight for each feature.
Data-driven styling enables you to highlight an area that is
important to your users. Style a polygon to provide context or focus
the user's attention on an area of interest important to your use
Utilize rich boundary data from Google. Access feature data for
administrative areas such as countries, localities, postal codes and
more. Visit the Google boundaries coverage page to view coverage on
a country-by-country basis, and use the viewer to search for
boundaries by name.
Click on the blue dots in this map to explore places listed in

Enhance your tabular business data with Google’s administrative
boundaries to create choropleth maps that tell stories through data,
allowing fluctuations in metrics to be visualized across a region.
Choropleth maps can be used to style multiple administrative areas
such as countries, localities, postal codes and much more. Use your
data to style an administrative area boundary by a range of data,
such as home prices, hotel nightly rates, health metrics, flood
zones and election results.
Use the region lookup utility to find the Google boundaries you want
to enhance to your tabular data with. Click the icons on the right
to see examples of choropleth maps that are styled by the number of
points of interest per boundary.
Data-driven styling provides support for interactive user
experiences through click events, which return metadata to your
apps, including Place ID, feature type, and display name of the
clicked polygon. These events are useful for experiences where you
wish to restyle the map based on user interactions.
The Place ID shown here can be used to apply styling to a specific
polygon in a feature layer, such as a specific city or country.
