A Mapbox GL map visualizes Japanese towers with observation decks, displaying each as a stack of extruded circular layers whose heights encode tower height. D3.js parses CSV data, while Turf.js generates circular geometries at each tower’s coordinates, and Mapbox’s fill-extrusion layers render them with a gradient color scale. Hover interactions reveal the tower name and heights, sourced from the Kiso Sansen Park and social statistics datasets.
