{"version":"1.0","type":"rich","title":"experiments","description":"This example shows a world map with a graticule and a rectangular polygon overlay, rendered as SVG paths. Users can drag to rotate the projection and zoom to rescale the view. It uses `d3.geoEquirectangular` with `d3.geoClipPolygon` to clip the sphere, `d3.geoGraticule` for the grid, and `d3.geoPath` for rendering. Country boundaries come from TopoJSON data in the world-atlas package, with drag handling via `d3.drag` and zoom via `d3.zoom`. The polygon overlay is outlined via `arc.outline()`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0dda4d39c13544f8a9a3b1e0bde0f994?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
