{"version":"1.0","type":"rich","title":"Question 1 – World Population Map","description":"This choropleth map displays world population data for select countries, using a blue sequential color scale to encode each nation's population in millions. The visualization is built with D3.v7 and topojson-client, loading geographic boundaries from a world-atlas dataset and using a Natural Earth projection via `d3.geoNaturalEarth1`. Hovering over a country triggers a tooltip showing its name and population, with `d3.scaleSequential` and `d3.interpolateBlues` driving the color mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3e938b46851445e1a1a94353466a03c1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
