{"version":"1.0","type":"rich","title":"Fork of World Choropleth","description":"This interactive choropleth map visualizes world countries colored by economy type, using a Natural Earth projection rendered as SVG through `d3.geoPath` and `geoNaturalEarth1`. The map, populated with country boundaries from TopoJSON and attribute data from a TSV source, supports zooming via `d3.zoom` and displays detailed country information—including population, GDP, and continent—in a custom tooltip on hover. A clickable legend highlights countries matching each economy category, while country labels are placed with overlap detection to maintain readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4ec01c35544d49f4b45b8b472e659f97?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
