{"version":"1.0","type":"rich","title":"New Technique","description":"This choropleth map visualizes global COVID-19 vaccination rates, specifically the percentage of each country’s population that is fully vaccinated, using a red sequential color scale. Hovering over a country highlights its border and displays a tooltip with the country’s name and vaccination percentage. The visualization uses the `d3.geoAzimuthalEqualArea` projection, `d3.geoPath`, and `d3.csvParse` to load and render geographic and CSV data, with a custom ordinal color legend built via `d3.scaleOrdinal`. Data comes from a local CSV file and world atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/157b091a90914af2a6ee3686dff06f02?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
