Observable Notebooks Data Loaders

The cell above is JavaScript that runs in Node.js, unlike normal JavaScript cells that run in the browser. The output of a data loader cell is automatically saved to a .observable/cache directory on your local file system alongside your notebooks. Data snapshots are stable — the data only updates if you re-run the data loader cell. In Observable Desktop, you can re-run a data loader cell by clicking the Play button, by hitting shift-return, or by clicking on the query age in the cell toolbar. In Notebook Kit, delete the corresponding file from the .observable/cache directory; you can also use continuous deployment, such as GitHub Actions, to refresh data automatically.
