{"version":"1.0","type":"rich","title":"Map with Selectable Countries","description":"This example shows a choropleth map where clicking a country highlights it and dims all others, with a color legend on the side. It uses the d3.geoPath and d3.geoNaturalEarth1 projections to render the world map, while d3.scaleOrdinal and d3.schemeSpectral define the color encoding. Country data comes from world-atlas TSV and TopoJSON files, and interactions trigger re-rendering with updated opacity and stroke styles. The map supports zooming via d3.zoom.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
