{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map colors countries by their economy classification using a sequential ordinal color scale, with an interactive color legend and hover effects that highlight individual nations. The visualization loads world geometry from a TopoJSON file and joins it with tabular TSV data containing country identifiers and economic attributes. Built with D3 v5, it employs `d3.geoPath` with a natural Earth projection, `d3.scaleOrdinal` for color mapping, and `d3.zoom` for panning and zooming. The SVG rendering includes a custom legend component that updates based on the color scale’s domain.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9bcacf58066c466dbcca8787e87f2d56?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
