 2. Install the visualizations into Jupyter as an nbextension.
   * If jupyter was installed with pip, you can use ```jupyter nbextension install facets-dist/ ``` if jupyter was installed system-wide or ```jupyter nbextension install facets-dist/ --user``` if installed per-user (run from the facets top-level directory). You do not need to run any follow-up ```jupyter nbextension enable``` command for this extension.
