{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map visualizes world countries using a natural Earth projection, with color encoding driven by data loaded from the world-atlas TopoJSON and TSV files. The SVG rendering uses `d3.geoNaturalEarth1` and `d3.geoPath` to draw geographic features, while an ordinal color scale maps country attributes to fill colors. Interactive pan and zoom are enabled through `d3.zoom`, which transforms both the map and sphere layers. A color legend is positioned on the left side to interpret the scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4502ec42c04945a7871d46c1747e8c41?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
