{"version":"1.0","type":"rich","title":"Chloropleth Map with interactive filtering-1","description":"A choropleth map displays global economic classifications, with a linked color legend for interactive filtering. Clicking a legend category dims non-matching countries and highlights those selected. The visualization uses d3.geoNaturalEarth1 and d3.geoPath for projection, d3.zoom for panning, and d3.scaleOrdinal with schemeSpectral for colors. Data comes from TopoJSON world-atlas and TSV metadata, rendered as SVG paths with hover effects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/44b4363442614e319f7731c7413dee90?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
