{"version":"1.0","type":"rich","title":"Fork of Fork of Fork of D3 Starter-maps","description":"This choropleth visualizes global population using a Natural Earth projection. Countries are drawn as SVG paths via `d3.geoPath` and a `d3.geoNaturalEarth1` projection, with fill colors assigned from a sequential blue scale (`d3.scaleSequential`) based on population values from a CSV. Countries lacking matching population data receive a random light blue fill. The map uses TopoJSON for feature parsing and is rendered at full viewport size.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/60888d3241094423b64f8dffa73b1896?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
