{"version":"1.0","type":"rich","title":"World Map","description":"This example displays a natural Earth projection world map with graticule lines, country borders, and interior boundaries. City populations are plotted as semitransparent circles with radii scaled by the square root of population using `d3.scaleSqrt`.\n\nThe visualization uses React hooks to load world atlas TopoJSON data and a CSV of global cities, converting them into GeoJSON features via `topojson.feature` and `topojson.mesh`. D3’s `geoNaturalEarth1` projection and `geoPath` render the SVG shapes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/349645543e2945e092b4e57074d02fde?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
