An interactive slide deck uses Odyssey.js to present a sequence of map-based story slides, with a CartoDB basemap and optional CartoDB layers loaded from a `vizjson` URL. The story advances through sequential triggers, responding to keyboard arrow keys and on-screen next/prev buttons, while a dot progress indicator tracks the current slide. The code also adapts slide layout to window resizing and adjusts the basemap’s tile URL when the global `baseurl` changes, relying on Leaflet and CartoDB’s JavaScript library for map rendering.
