I put together a GitHub Gist with a generated GeoJSON document, along with the bash command that was used to create the data.
GitHub automatically generates maps for GeoJSON files in Gists and repositories. This is well documented at the following article:
The script pulls data from eBird API, transforms the data structure into GeoJSON format using jq, and then POSTs the result to a GitHub Gist where it is displayed as an interactive map.
