{"version":"1.0","type":"rich","title":"Fork of Polished World Map","description":"This example shows a world map with country boundaries, graticules, and city points sized by population. The visualization uses a Natural Earth projection via `d3.geoPath` and `d3.geoNaturalEarth1`, with land and interior borders rendered from World Atlas TopoJSON. City data comes from a CSV of world cities, and circle radii are scaled with `d3.scaleSqrt` based on population. The map is built with React components, styled in SVG, and uses D3 v5 for geographic and data-processing tasks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5f5ee875cffa4e71926e1b8776281e3d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
