Scatter lines graph not rendered in v6.1.2

[jochen-schuettler]

I'm using plotly to visualise measurement data from inside a Raspi 3b, serving the result with Dash and Flask, which worked beautifully until plotly v5.24.1.

Now, with plotly v6.1.2 I only see empty graphs. Explicitely setting line parameters changes nothing.

This is plotly-relevant code:

import plotly.graph_objs as go
    fig = go.Figure(
        data=[go.Scatter(x=x, y=y, mode='lines', name='test')],
        layout=go.Layout(
            xaxis=dict(title='time', rangeslider=dict(visible=True)),
            yaxis=dict(title='data'),
            margin=dict(l=40, r=20, t=30, b=40),
            hovermode='closest',
        )
    )
