{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map visualizes epidemic risk across countries, using color intensity to show the P2P risk index and a legend with ordinal color swatches. The map is rendered with SVG paths generated by `d3.geoPath` and a `geoNaturalEarth1` projection, with TopoJSON data from the World Atlas and risk data from a CSV file. Hovering highlights a country, and missing data appears gray. Users can zoom and pan the map via `d3.zoom`, while `scaleOrdinal` and `schemeRdPu` drive the color encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d3e854116a7f4796a3d6b68b54641762?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
