{"version":"1.0","type":"rich","title":"Choropleth map","description":"This choropleth map visualizes annual population growth rates by country for 2017, using a diverging color scale from indigo (negative growth) to white (no change) to dark green (positive growth). The visualization renders world country shapes using D3’s `geoEqualEarth` projection and `geoPath`, with graticule and sphere overlays. It loads World Bank data from a CSV and geospatial data from GeoJSON, and includes an interactive tooltip on hover plus a user-location marker via the Geolocation API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c2574bb76b7e440fb16d62239dcd6ecc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
