plotly basic example shows no plot in jupyter lab

Question

I just tried to use plotly offline in a jupyter notebook (using jupyter lab). The docs gives this example:

import plotly
import plotly.graph_objs as go

plotly.offline.init_notebook_mode(connected=True)

plotly.offline.iplot({
    "data": [go.Scatter(x=[1, 2, 3, 4], y=[4, 3, 2, 1])],
    "layout": go.Layout(title="hello world")
})

I tried it and there is no chart displayed, either in Edge or Firefox.
An output cell is made in the notebook, but there is no chart.

It works if I use plotly.offline.plot rather than iplot. It works if I use the traditional jupyter notebook rather than jupyter lab.

Any ideas why it does not display?

It's plotly version 2.7.0.

Have you installed Plotly JupyterLab extension? It will not work inline without it. You can get it here: https://github.com/jupyterlab/jupyter-renderers/tree/master/packages/plotly-extension

or just install via terminal: jupyter labextension install @jupyterlab/plotly-extension

Installed Node.js 10.16.0 using the windows installer, but when I executed the terminal command, I get the error "ValueError: Please install nodejs 5+ and npm before continuing installation...". Not sure how to make jupyter lab recognize/find what it needs. – Michael Szczepaniak Jun 11 '19 at 03:31

I don't have enough points to add the comment: The @jupyterlab/plotly-extension has been deprecated in favor of the plotly supported render extension, which is at: https://www.npmjs.com/package/jupyterlab-plotly.

Install via:

jupyter labextension install jupyterlab-plotly
