You simply move a folium map viewer to any location you want, and then click a button that transforms it into a ridge map. You can fully customize the map with different vertical angles, line widths, and color schemes, to name a few options.
Thanks for user testing the app @rcsmit! And nice map! I isolated the issue to the bounding box coordinates of the visible area of the folium map being wrongly updated when moving westward from western hemisphere to eastern hemisphere. Mapping any place on the globe still works when moving the browsing window of the folium map eastward to the eastern hemisphere. I’ll implement a fix later this week.
