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.
