{"version":"1.0","type":"rich","title":"Visal Refusals Choropleth Map","description":"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.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c0f0b096e0814f00bb2c41791a8568f7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
