{"version":"1.0","type":"rich","title":"Interactivity in Choropleth Map","description":"This interactive choropleth map visualizes global economic data, coloring each country on a natural Earth projection according to its economy category. Users can click a country to highlight it, dimming all others, or click a color legend to filter countries by economic classification, which also outlines matching countries in red. The example uses d3.geoPath for map rendering, d3.scaleOrdinal with a spectral color scheme, and d3.zoom for pan and zoom interactions. Country data is loaded from a TopoJSON file combined with a TSV file containing ISO country codes and economic classifications.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5516eb417f7f4b35be73890803eeed9c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
