task 1
This choropleth highlights the top five least peaceful countries—Russia, Ukraine, Sudan, DR Congo, and Yemen—with a dark-to-light red ordinal color scale indicating rank, while all other nations remain muted gray. Using D3 v7 with `d3.geoNaturalEarth1` projection and `d3.geoPath`, it renders world GeoJSON data from Natural Earth onto an SVG. Interactive tooltips appear on mouseover, displaying each country’s name and rank, powered by D3 event handlers. The visualization demonstrates a configurable `Map` of ISO-3 codes to adjust highlighted countries.
