{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map displays countries of the world colored in light green, with a blue sphere representing the globe and black borders between nations. The visualization uses `d3.geoNaturalEarth1` projection and `d3.geoPath` to render geographic features from TopoJSON data, while country names come from tab-separated values (TSV) data. Interactive zooming is implemented with `d3.zoom`, converting events to SVG transforms. Hovering over a country changes its fill color to red through CSS `:hover` styles, and tooltips with country names appear via SVG `title` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e74f7802a0d14ee4af51b8c57c05470d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
