{"version":"1.0","type":"rich","title":"US vs the World (Visa Refusals)","description":"This choropleth visualizes visa refusal rates by country, using a yellow-or-brown color scale to indicate economic classification rather than refusal counts. The map, rendered as an SVG with a blue sphere background, uses a natural Earth projection and supports zooming. Data is loaded from the World Atlas TopoJSON and TSV files, with each country’s path colored via `d3.scaleOrdinal` and `schemeYlOrBr`. A custom color legend shows the ordinal categories, while hovering highlights a country in red and displays its name and economy type in a tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d141c3d28a9b41bd91cc841fa81e0cc8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
