{"version":"1.0","type":"rich","title":"Activity-8.5.1","description":"This example displays an interactive world map using a spherical projection, rendered as SVG paths. It loads geographic data from a TopoJSON file via `world-atlas@2`, converting it to GeoJSON features with `topojson.feature`. The visualization supports zooming through `d3.zoom`, and styles continents with `d3.geoPath` and `geoEquirectangular`. Hovering over countries changes their fill color to maroon.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b85a09d4b332478981e4ee07cbe6dd9d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
