Graphs may not show sometimes

[yuhanchen0711]

Sometimes I may put an array of express.scatter3d and have it return as a child. Unfortunately, in this case sometimes some of the graphs cannot load.

Thanks for your bug report - can you please provide a minimal reproducible example so that we know exactly what you're trying and have somewhere to start debugging? thanks - @gvwilson

I'm going to guess this is about running out of webgl contexts https://plotly.com/python/webgl-vs-svg/#multiple-webgl-contexts.

Looks like you're in Dash @yuhanchen0711 - see my comment in https://github.com/plotly/dash/issues/2740:

It can already be done by adding https://unpkg.com/[email protected]/src/virtual-webgl.js to external_scripts (or downloading that and putting it in your assets folder), so we could just document that, but it would be nicer to have a built-in way to do this.

I will transfer this issue to the Dash repository and flag it as needing documentation - thank you.
