{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This choropleth map displays country-level economic data using a color scale, with a legend allowing viewers to filter the map by clicking a specific economic category. The map uses a natural Earth projection through `d3.geoNaturalEarth1` and `d3.geoPath`, rendering country boundaries as SVG paths. Filtering dims non-selected countries and highlights the chosen one, while the legend’s interactive ticks use `d3.scaleOrdinal` and `schemeSpectral` for colors. Data is loaded from the world-atlas TSV and TopoJSON files, with interactive zoom via `d3.zoom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/053c16c8c90548a099cb54bdbfac6103?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
