{"version":"1.0","type":"rich","title":"Chloropleth Map","description":"This choropleth map visualizes world countries with a natural Earth projection, coloring each nation light green and highlighting it red on hover. The visualization loads geographic data from the world-atlas TopoJSON and tab-separated country names, merging them by ID before rendering. Using D3 v5’s `geoNaturalEarth1` projection and `geoPath` generator, it draws SVG paths for each country, while TopoJSON’s `feature` API converts the topology into GeoJSON. A semi-transparent black stroke outlines national borders, and a blue sphere background represents the globe. Tooltips display country names via appended `title` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c717edd167a541f4ac44a520f2c9b72a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
