Unrenderable violin plot

[slambert-git]

I have some example input here and a script for creating a violin plot. The plot writes without error but appears unrenderable, it never displays and will e.g., cause notebooks to crash.

Python 3.13.5
plotly 6.0.1
pandas 2.2.3

import pandas as pd
import plotly.express as px
from plotly.graph_objects import Figure


def create_plot(df: pd.DataFrame) -> Figure:
    fig = px.violin(
        df,
        color='sample',
        color_discrete_sequence=px.colors.qualitative.Safe,
        y='value',
        x='sample',
        points=False,
        box=True,
        facet_col='metric',
        facet_col_wrap=1,
    )
    fig.update_yaxes(matches=None)
    fig.update_xaxes(matches=None)
    fig.update_layout(height=400 * len(df['metric'].unique()))
    return fig


if __name__ == '__main__':
    file = 'df_melted.csv'
    df = pd.read_csv(file)
    fig = create_plot(df)
    fig.write_html('test_plot.html')

Example input file is attached. The input is admittedly unusual for a violin plot (essentially all 0s or all 1s).

Thanks in advance!
