Problem:
Since v6.0.0 FigureWidget uses anywidget. However, it fails with a java script error.

Workaround:
Downgrading to plotly-5.24 solves the problem

Maybe somewhat related to #4996

    Could you describe the way that you installed anywidget? I was seeing this issue when I installed anywidget while JupyterLab was running without restarting it. I'm curious if restarting JupyterLab / reloading the page would help. (Still a bug, just good info for debugging)

    @marthacryan I created a fresh venv with python3.11 and run pip install plotly anywidget and run the code in vscode notebook. I also restarted the kernel several times, somties just no output is shown, somtimes the json error. I also tried to run it in google colab. There, I don't see the json error, but also get no output (the figure is not shown).

    Thank you for the info @turbotimon! Looks like this is an issue with plotly.js==3.0.0, which we updated to for the plotly.py==6.0.0 release. I'll investigate why this is happening but as a note, I think it may be related to removing require.js and needing to update the way that we include plotly.js.

    Update here: looks like there is a PR open that does fix this issue for plotly.js: plotly/plotly.js#7367.

    Plotly.js just released the 3.0.1 patch which will fix this! We'll need to update the plotly.js version in plotly.py, so I'll wait on that to close this issue.

    Hi,
    I'm having this issue too. Could any one suggest how to I apply patch to my existing installation of plotly in Python?

    You can't upgrade?

    Upgrade or downgrade, just don't use v6.0.0, e.g.: pip install plotly!=6.0.0

    @turbotimon Is this now working for you?

    With 5.24 it is, I did not try it with 6.0.1 yet..

    Edit: Just tried with 6.0.1 in colab. It works but behaves different, a single fig or fig.show() at the end of the cell won't show the plot (as it did in 5.24), but a display(fig) will. @marthacryan is this a "feature or a bug" and is this due to your #4869?

    Test code:

    # %%
!pip install -U plotly anywidget
# %%
import plotly.graph_objs as go
fig = go.FigureWidget()
fig.add_scatter(y=[2, 1, 4, 3])
fig # does not show anything!
# %%
display(fig) # but this
# %%
from ipywidgets import widgets
button = widgets.Button(description="foo")

def on_button_clicked(b):
    fig.data[0].y = [1, 2, 3, 4]

button.on_click(on_button_clicked)
button # test the change

    Edit2: It seems that this behaviour is only in colab. But it seems to work in e.g. vscode notebooks. I did not try it in jupyter lab. Versions used plotly==6.1.2 anywidget==0.9.18

    Oh interesting @turbotimon I'm seeing the same behavior in colab. This must be a difference in how they handle displaying widgets. I think for now using the display function in colab seems like a good workaround.
