# Accessing Exernal Data

External data, such as third-party APIs, can be used in place of geospatial or tabular data. By default, any [Cross-Origin](/data/external-data.md) accessible `GeoJSON` URL can be used in place of a file in `public/geojson` when speccing out your [datasets](/data/external-data.md), and any `CSV` URL can be used instead of a local file.

Due to the structure of the binning algorithms and clustering analyses at the core of WebGeoDa, tiled data are not currently supported for choropleth layers.

## Coming Soon

* Google Sheets Support
* JSON endpoint support
* Firebase
* Hasura / Supabase
* Elastic Search
* Datasette
