 In **Plotly.py 6.3 and later**, the built-in countries geometry is created from the following sources:
-- [UN data](https://geoportal.un.org/arcgis/sharing/rest/content/items/d7caaff3ef4b4f7c82689b7c4694ad92/data) for country borders, coastlines, and land layers.
-- Natural Earth data for oceans, lakes, rivers, and subunit layers.

 In **earlier versions of Plotly.py**, the built-in countries geometry is based on Natural Earth data only. Plotly includes data from Natural Earth "as-is". This dataset draws boundaries of countries according to de facto status.
