Might not be what you're looking for, but about 2 years back now I built a little tool that does something similar to this (not SVG) and no special coding/skills required

Check out the sample story here: https://turas.app/s/japan-x-taiwan/BtEjycbA

As you scroll down past the days, it will show the map and places for each day (on desktop).

The front-end of this is a planning app for planning the itinerary and the "story" is one output of the planner.
