{"version":"1.0","type":"rich","title":"Locator Map","description":"This locator map displays London, UK, as the central point, surrounded by major cities with population data plotted on a Mercator projection. It uses D3.js's `geoPath` and `geoMercator` for geographic projection, `geoGraticule` for the reference grid, and RBush for collision detection to intelligently label cities without overlap. The map includes a scale bar and city labels, with data sourced from TopoJSON world geography and a CSV of world cities.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f71f9c5a51b04518bd2e9196c4ff84b6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
