{"version":"1.0","type":"rich","title":"Q1_Ice8","description":"This choropleth map visualizes world population data by country, using a Plasma color scale to represent population magnitudes. Built with D3 v7 and TopoJSON, it loads countries-110m.json and a CSV population dataset, then renders each country as an SVG path via `d3.geoPath` with a Natural Earth projection. Hover interactions trigger a tooltip displaying country name and population, while a color legend explains the scale. Countries without data appear gray, and the map refreshes with smooth transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2f691f35293c4fe5aa533ea983a5f9c8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
