Build a guide book as a map?

Is it possible to use open street maps to build something like the google map that is used on atlas obscura(https://www.atlasobscura.com/articles/all-places-in-the-atlas-on-one-map) with large clusters and the possibility to start the zoom at specified regions/cities?

There is Leaflet. You should be able to write yourself something similiar with this library.
