{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"This interactive SVG world map highlights five countries colored by population size, with India and China appearing darkest on a blue sequential scale. The visualization loads world geometry from the world-atlas TopoJSON dataset, then uses `topojson.feature` to extract country boundaries and `d3.geoPath` with a Natural Earth projection to render them. The D3 v7 code joins the TopoJSON features with the CSV-derived population data by country name, applying a tooltip on mousemove to display exact population figures. Countries lacking data render as gray.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/428948d605a1438885462e5be183975f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
