JavaScript Issue resolution in JupyterLab Notebook

The graphs are not appearing in JupyterLab Notebook and the error message says “JavaScript output is disabled in JupyterLab”.

At first, it seems that from Notebook itself I just need to enable it but few site says it Jupyterlab does not support it yet is frustrating.

#matplotlib submodule pyplot

import matplotlib.pyplot as plt

x = np.arange(0,100,0.5)

y = 2 * np.sqrt(x)

plt.plot(x,y)

plt.show()
"JavaScript output is disabled in JupyterLab"

C:\Users\victor>jupyter nbextension enable --py --sys-prefix widgetsnbextension

Enabling notebook extension jupyter-js-widgets/extension...

- Validating: ok

Now invoke “jupyter lab” and you can see your plots:
