{"version":"1.0","type":"rich","title":"World Map-Grayscale","description":"This example displays a grayscale world map with country boundaries, graticules, and a subtle sphere outline. It uses the `geoNaturalEarth1` projection and `geoPath` from D3 v5 to render geographic features as SVG paths. The map is built from World Atlas TopoJSON data, processed with the `feature` and `mesh` functions from topojson to extract landmasses and interior borders. The visualization is constructed as a React component, with a grayscale color scheme for the land and graticules.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/29d53419cef649468e9feb6b59ecc6ea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
