{"version":"1.0","type":"rich","title":"Fork of Map","description":"This choropleth map displays a \"Literary Population Score\" for selected countries, using a blue sequential color scale to represent values from 0 to 100. It loads world geometry from a TopoJSON file via `d3.json` and converts it to GeoJSON features using topojson, then draws the countries with `d3.geoPath` and a Mercator projection. Country fills are determined by looking up three-digit numeric ISO codes in a `Map`, with tooltips showing names and scores. A vertical legend uses `d3.scaleSequential` and `d3.interpolateBlues` to explain the color mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3418b402cb094f47be6cae4616f1fde9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
