{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A choropleth map of global economic data, colored by country using a spectral ordinal scale, lets viewers filter countries by clicking a color legend. The map renders with an SVG projection via `d3.geoNaturalEarth1` and `d3.geoPath`, supporting pan and zoom through `d3.zoom`. Legend clicks toggle highlighting of matching countries, dimming others. Country data merges TopoJSON geometries with TSV attributes from the world-atlas dataset, and legend interactions redraw both map and legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0e617810e4884bc180f6103774114467?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
