{"version":"1.0","type":"rich","title":"world chart","description":"This example displays a world map using a Natural Earth projection, showing country boundaries and graticule lines over a light gray sphere. The visualization loads geographic data from a TopoJSON file using `d3.json`, then converts it to GeoJSON features and interiors with `topojson.feature` and `topojson.mesh`. React renders the map as SVG paths computed by `d3.geoNaturalEarth1` and `d3.geoPath`, with styling applied through CSS classes for the sphere, graticule, and country fills.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5bc08394a56d4ddabd206040e3e32f07?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
