Prevent calling scrollToPart if node is x% (or majorly) visible on viewport

Hi Walter,

In my diagram, when a node not completely visible on viewport is selected, I am calling scrollToPart to make the node visible in the viewport. I am using below to check the visibilty condition -


Now, I have a requirement where -

Can you please help?


I would compare the area of the node (its actualBounds) with the area of its intersection with the viewport:
