{"version":"1.0","type":"rich","title":"RS Choropleth Map","description":"This choropleth map colors world countries by economic category using a spectral ordinal color scale, with countries labeled on hover and a color legend rendered as circles. The visualization uses the `d3.geoNaturalEarth1` projection, `d3.geoPath` for drawing country boundaries, and `d3.scaleOrdinal` with `d3.schemeSpectral` for coloring. It loads world-atlas TopoJSON and TSV data, processes it with `feature` from topojson, and renders to SVG. The map supports pan and zoom via `d3.zoom`, and includes interactive hover highlighting.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/00b0da0924064cb2bfb0dcb4a61ec6ba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
