Interactive map of the convenience store "turf war" in Japan

This interactive map reveals the territorial battles between Japan's major convenience store chains. Discover which chain dominates each region and get insights into the competitive landscape of Japan's convenience store industry. Technologies used: Leaflet (frontend) Turf (Geojson generation and Voronoi generation) I noticed that my neighborhood is all Lawsons, so I got the location of all Conbinis and ran some basic analysis to see if these pockets of brand territory are common.
