{"version":"1.0","type":"rich","title":"Choropleth Map Interactivty selection","description":"This example shows an interactive choropleth map where clicking a legend category highlights matching countries and dims all others. Built with D3 v5 using `d3.geoMercator` and `d3.geoPath` for SVG rendering, it also applies `d3.zoom` for panning. The legend uses `d3.scaleOrdinal` with `schemeSpectral`, and click events toggle the selected category. Data comes from the World Atlas TopoJSON and TSV files, loaded via `Promise.all`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7eaeaf1d46db4c81aaf5f1dcd53b027d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
