{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map displays global economic classifications, with countries color-coded by their income group using a spectral ordinal scale. Users can click legend items to highlight matching regions, which dims non-selected countries and increases their stroke width. The visualization uses d3.geoNaturalEarth1 and d3.geoPath to render GeoJSON from the world-atlas TopoJSON dataset, while d3.zoom enables interactive panning and zooming. A custom color legend with clickable circles and d3.scaleOrdinal drives the selection filtering, rendered entirely as SVG elements within a React framework.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9f24f85d05c64e5f9faadd4cf258b176?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
