{"version":"1.0","type":"rich","title":"ice8_task1","description":"This interactive map shows world countries on an orthographic globe projection, where users can drag to rotate the sphere and click on a country to switch between the orthographic, Mercator, and Albers USA projections. The visualization uses D3's geo-projection modules—`d3.geoOrthographic`, `d3.geoMercator`, and `d3.geoAlbersUsa`—along with `d3.geoPath` to render country boundaries, graticules, and a sphere outline. Country names and geometries come from the world-atlas TopoJSON and TSV datasets. Zoom and pan are implemented via custom drag and zoom interactions, with smooth animated transitions on projection changes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/89b6e02462a546f082567a37d21fa5c3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
