{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"This visualization shows a world map with countries colored by population using a threshold scale, rendered as SVG paths via `d3.geoPath` with a Mercator projection. The choropleth uses a quantized color range from light to dark blue, and hover interactions trigger tooltips built with `d3-tip`, displaying each country’s name and population. Data comes from a TopoJSON file and a TSV of population figures, both loaded asynchronously with the queue library.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f8b064d14b194fea8eb5f259cb606e61?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
