Thanks for these explanatory videos - they help a lot!

What about adding an additional trace to an existing figure? Does the existing add_trace function also re render the entire figure? Could it be done with patch? Essentially adding data to a figure that does not already exist on the figure.

Thanks for explaining Patch, I didn't know it. My figures generally have 100k up to ~1000k points. When I change some selectors, the whole Graph needs to be updated. Will patch still have an advantage in this case or only if some datapoints need an update?

if the whole graph has to be updates with all new points, I don't think Patch would be very useful.
