Improved performance

The rendering engine is optimized to handle larger datasets with reduced rendering times, especially for scatter plots and 3D charts.

python 
import plotly.express as px
import numpy as np

# Performant scatter with 100k points
np.random.seed(42)
n = 100_000
fig = px.scatter(
    x=np.random.randn(n),
    y=np.random.randn(n),
    opacity=0.3,
    title='100k points - optimized rendering',
)
fig.show()
