Data-driven styling for datasets
You can upload your KML data as a dataset and use data-driven styling to display it on the map. This approach offers better performance and more styling options.
To get started with datasets, read the Datasets Overview.
Third-party libraries
You can also use third-party libraries to parse KML files in the browser and display the data using the Maps JavaScript API's Data layer or other overlays.
Popular third-party libraries for parsing KML include:
- togeojson (converts KML to GeoJSON)
- fast-xml-parser
Once you have converted the KML data to GeoJSON, you can load it into the
Data layer using map.data.addGeoJson().
