{"version":"1.0","type":"rich","title":"World Map","description":"This example renders a world map from TopoJSON data using D3 v5 and React, drawing countries as filled paths on an SVG canvas. The visualization uses `geoEqualEarth` for the projection, `geoPath` to generate paths, and `geoGraticule` to display a graticule overlay, with a distinct red sphere background and blue landmasses. Country geometries are loaded from the world-atlas TopoJSON file and converted to GeoJSON via `feature()`. The React component hierarchy separates data loading (`useData`) from the presentational `Marks` component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b26b59ad5fbe401680ef3125a2644799?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
