{"version":"1.0","type":"rich","title":"Fork of Fork of D3 Starter-maps","description":"This choropleth displays world population figures for a selection of countries, with darker blues representing higher populations and gray for countries without data. It uses a Mercator projection via `d3.geoMercator` and `d3.geoPath` to render country boundaries from a TopoJSON world-atlas dataset. Population values are mapped through a sequential `d3.scaleSequential` with an `interpolateBlues` color scale. Hovering reveals a tooltip with the country name and population in millions, powered by SVG `title` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fd817784c7b64d49b71cf4c58fec9e2d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
