By default, IPython (kernel of Jupyter/Lab notebook) disables executation of untrusted code without explicit user input. If you have notebook whose output containings JavaScript (e.g., JS-based visualiation) and code wasn't run by you (e.g., the notebook is shared by someone else), the JS-based output won't be shown by default. For more explanation, please refer to Notebook Security.
There are currently 2 ways to trust a notebook. First, you can trust (multiple) notebooks via command-line.
