{"version":"1.0","type":"rich","title":"Untitled","description":"This example displays a world map colored by continent, with each landmass labeled at its geographic centroid. It uses a Natural Earth projection with a slight rotation, rendered as SVG paths. The code loads TopoJSON data, converts it to GeoJSON features via `topojson.feature`, and projects centroids using `d3.geoCentroid` and `d3.geoPath`. Continent colors are assigned from a hardcoded array, and labels are appended as SVG `<text>` elements. The visualization relies on d3.v4, topojson.v2, and d3-geo-projection.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/52750f0cc559478cbd41d5ee50ded95d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
