{"version":"1.0","type":"rich","title":"Fork of Data Viz Project","description":"This choropleth map visualizes estimated population by country, with color encoding from light blue to dark blue based on population magnitude. It uses D3 v7's `geoMercator` projection and `geoPath` to render world country boundaries from TopoJSON data in World Atlas. Population values come from the accompanying TSV file, which maps ISO country codes to their `pop_est` estimates, and a `scaleLinear` determines the fill color per nation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9e7e19a53592442a8a89c9c56d43e1ce?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
