{"version":"1.0","type":"rich","title":"Choropleth Map Interactivty selection","description":"This example visualizes the World Bank’s country-level economy classifications on a choropleth map. Users can select a specific economy class from the color legend, which highlights matching countries and dims all others, while hovering over a country reveals its name and economic category. Built with d3.js v5, the map uses the `geoMercator` projection and `geoPath` to render country shapes from TopoJSON data. The legend, implemented with `scaleOrdinal` and `schemeSpectral`, enables interactive filtering through mouse clicks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5bc3f18267634735802f510b3945e031?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
