{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map displays world countries in green with a dark blue ocean sphere, highlighting each country in red on hover. Using D3 v5 and TopoJSON, it loads world-atlas data (50m resolution) to generate SVG paths via `d3.geoPath` with a `geoNaturalEarth1` projection, matching ISO country IDs to names from a TSV table. The map supports zoom and pan interactions through `d3.zoom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2ba5f2cbf75044e8bf176d0cf4b02278?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
