{"version":"1.0","type":"rich","title":"Maps","description":"This choropleth map visualizes world population by country using a blue sequential color scale. It loads GeoJSON country boundaries and a CSV of population data, joining them by ISO3 country codes. The map is rendered with D3.js, using `d3.geoNaturalEarth1` projection and `d3.geoPath` to draw SVG paths. Countries with missing data are shown in gray. Hovering over a country reveals a tooltip with the country name and formatted population. A gradient legend displays low-to-high population values with tick marks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/abb1c263c3344b7f8c6b5c56460f2634?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
