Visal Refusals Choropleth Map
✓ Published0🌍 Public
A choropleth world map visualizes visa refusal rates by country for 2019, with a yellow-orange-red sequential color scale indicating increasing refusal counts and gray for missing data. Built with React and D3 v5, it uses `geoAzimuthalEqualArea` for projection, `geoPath` for rendering country boundaries, graticules, and sphere outlines, plus `scaleSequential` with `interpolateYlOrRd` for coloring. Country codes are matched from ISO data, and country shapes come from World Atlas TopoJSON.
