{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"This example displays a world choropleth map coloring countries by their economic income group, with a categorical color legend and zoom/pan functionality. The visualization uses D3 v5 APIs including `geoPath` with `geoNaturalEarth1` projection, `scaleOrdinal` with `schemeSpectral` for color mapping, and `zoom` for interaction. It loads geographic data from the world-atlas TopoJSON and TSV files via `topojson.feature`. Countries render as SVG paths with hover highlighting, and the color legend dynamically generates from the ordinal scale domain.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a7952c2cfd9243acbd50f261bb687fbc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
