To open local files in the Voyager extension, right click on a valid file (JSON, CSV, TSV, vl.JSON) in JupyterLab's
Files tab, hover over
Open With, and click
Voyager. After opening your dataset in Voyager, you can visualize and explore your data as described in earlier sections of this documentation.
You can export visualizations from Voyager to a vl.JSON (Vega-Lite) file or Jupyter Notebook.
To save your visualization to a vl.JSON file, right click anywhere in the
Specified View pane, and click
Export Voyager as Vega-lite File. You can re-open this file later in the Voyager extension and JupyterLab's native Vega-Lite renderer.
To export your visualization to a Jupyter Notebook, right click anywhere in the
Specified Viewpane, and click
Save Voyager to Jupyter Notebook. JupyterLab will then prompt you to choose a Python Kernel. After selecting a kernel, the Altair code to generate your visualization will be injected into a notebook cell. Run the cell to display your visualization.
