This is great. I like the intuitive API. Perfect timing, too -- I needed to make a pie menu today for a virtual whiteboard. Currently thinking about how to incorporate hover effects and selection.

I had to add a bit of JS/CSS to get the "satellites" hoverable to my liking. The library gives you circle regions and capsules, and you could wrap each in a link or button tag, but that still leaves dead space between the pie slices. I ended up using some trig and pointer handlers. Not sure if I missed part of the docs, or if that's a consideration for future Orbit versions. Still a great library though.
I believe that "satellites" have pointer-events set to none by default. I would think in some solution, maybe adding a CSS utility to change that in case is needed
