How to create a web animation of the movements of an object in space over time?

I would like to create a website that shows an animation of the path of Sagittarius A* (or any other object in space) during one day for a specific location. So that the user can see where and when Sagittarius A* is rising, what path across the sky it takes and where and when it is setting.

Similar to this: https://www.youtube.com/watch?v=adJPV-sz5AI&t=58s

I know the animation in the YouTube video was made with "Stellarium Web" and I could make something like that with Stellarium for Sagittarius A*. But I would like to have it interactive on a website where the user only has to enter his current location and then would see the animation of the path for his location.

Any tips where to start or any existing projects/libraries on this?

What I tried is using this library: https://github.com/ofrohn/d3-celestial.
But the effect was not really like in the YouTube video above.
