Is it possible to visualize the annotations on the slide viewer with magnification self-adapted?

Here:
https://github.com/openslide/openslide-python/tree/master/examples/deepzoom/templates
these html files creates visualization of the multi magnification images of
the slides. Is it possible to add annotation lines on the visualization
given the corresponding annotation lines' coordinates like below (with
magnification self-adapted)?

Yes. Those visualizations use the OpenSeadragon viewer, which supports
overlays:

OpenSeadragon uses a different coordinate system than OpenSlide, so
coordinate conversion may be necessary.
