Research direction

Start by reproducing the failure with the supplied Python snippet, including the large scatter data and long text values, then compare fig.show() with fig.write_html('visualization.html'). Investigate how the generated HTML handles the hover_data payload; done means the resulting HTML opens and renders the plot reliably with long descriptions.

Description

bug P3

When trying to create a scatter plot with long descriptions (~5k chars), the html file stops running. Unfortunately, the description cannot be shortened. Here's a code snipped that will help reproduce the problem:

import numpy as np
import pandas as pd
import plotly.express as px

embedding2d = # generate np.array with shape: (389000, 2)
x = embedding2d[:, 0]
y = embedding2d[:, 1]
data = pd.DataFrame({
    'x': x,
    'y': y,
    'text': # generate list of 389000 samples with 10k chars each sample
})

# Визуализация с plotly
fig = px.scatter(
    data, x='x', y='y',
    #template='plotly_dark',
    hover_data=['text'],  # Добавляем данные, которые будут отображаться при наведении
    title="2D Vector Visualization with Labels",
)

fig.update_layout(
    width=1520, height=685,
    title_x=0.5
)

fig.show()
fig.write_html('visualization.html') # open browser

P.s. Changing browser doesn't help. I waited about 20 minutes
