How is this built? Is this built on d3.js? This reminded me of old flash style plugins which we don't see any more.

It's using Three.js[^1] with Photons[^2], and a number of other interesting libraries for calculation like satellite-js[^3].

This ux/navigation implementation is inspiring esp for mobile safari web browser. Intuitive and responsive, kudos to the devs

I don't know which framework they're using, if any, but this is WebGL2. You can write fairly modern OpenGL code and run it in the browser. :)
