Hi,

Is there a sample somewhere with million+ data points which have image displayed on scatter plot hover ? I was looking to see if there are any caching tricks and tips I can utilize in the hover template.

Hi,

I think the DataShader project is what you are looking for. You can find more info on the project repo page. You can also find the recordings of the webinar showcasing the project here.
