Too late to edit my original comment - but I added a subtle animation to the landing page to show that it's possible. http://jdan.github.io/isomer/ http://jdan.github.io/isomer/ (at the top) I'm redrawing the entire structure each time, though. You could optimize it manually by only redrawing surrounding polygons. Performance seems pretty good on my end, decent on mobile.
