Here’s one I made, using Carto:
This looks a bit closer to usable, though I don’t see much real style control when making the map. Maybe a little studying over at Carto…
Meanwhile, I tried one of my demo web pages that uses Leaflet, embedded in a test post, and it (the map) worked great. Unfortunately, the map itself was only one part of another website, and stuffing the entire thing into an iframe caused some display/clutter issues, so I decided to write another demo to see what I can do. This can sit and stew for a while, I think I got whatever out of my system — it’s time for a ride.
