{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This example shows a world map rendered as a choropleth using geographic boundaries. It displays landmasses with gray graticule lines, a black outline, and white borders between countries. The code loads GeoJSON data converted from TopoJSON using topojson-client, then renders it with d3.geoPath and a d3.geoNaturalEarth1 projection. It uses d3-geo utilities like geoGraticule and React-like state management through a custom viz pattern.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c86842fd4d1040128ab942fa47e2dcba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
