{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"This fork of a choropleth map colors countries by economy category using a spectral ordinal scale, with a legend rendered as circles and text. Built with D3 v5, it loads world geometry from TopoJSON and country metadata from TSV, then projects paths via `d3.geoNaturalEarth1` and `d3.geoPath`. Map panning and zooming use `d3.zoom`, while hover effects highlight countries in red. The legend is created by a custom `colorLegend` module that binds to color scale domains and updates in place.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9411eb261258488cb7ca57dc6dfaa288?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
