{"version":"1.0","type":"rich","title":"Untitled","description":"A choropleth map colors countries according to the number of students per country, with a sequential red color scale and a legend showing count ranges. The visualization uses D3 v5’s `d3.geoMercator` projection and `d3.geoPath` to render world topology from the World Atlas TopoJSON, while data from a TSV file is joined to country features. Country boundaries are styled with white strokes, and hovering highlights the selected country.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/97a0c2f7ad6a478baee6cad92413f6a8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
