That time when browsers rendered SVG funny if at all was not very long ago.

There’s another challenge: you need to provide more and more data as you zoom in, wonder how that should work with vector stuff.

This already handled afaict. When I zoom in on apple maps on a stalled data connection I can see the sharp edges of the low resolution vector data until the higher resolution data is downloaded.

SVG is convenient but isn't necessary.

On apple maps the app or on the web? Although I suspect that canvas + some homegrown vector engine it is.

The app. I'm not sure how the web interface behaves.
