{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"This choropleth map visualizes global COVID-19 vaccination rates, specifically the fully vaccinated population portion per country, using color intensity to show geographic disparities. The map renders countries as filled paths via `d3.geoPath` with a Natural Earth projection, while a `d3.scaleQuantile` maps data values to the `schemeYlGnBu` color scale, with gray for missing data. Data comes from a CSV file of vaccination statistics, parsed with `d3.csvParse`, and country boundaries use TopoJSON data processed through `topojson.feature`. The visualization updates asynchronously with `Promise.all` and `setState`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/db0a4cbe1ff9479b9cb15e0941144188?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
