{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"This choropleth map displays global economic classifications using a categorical color scale, with a legend that filters countries by clicking on a category to highlight matches and fade others. Built with D3 v5, it renders country shapes via d3.geoPath and TopoJSON data from the World Atlas, while the legend uses d3.scaleOrdinal with a spectral scheme. Zoom and pan interactions are handled through d3.zoom, and hovering changes a country’s fill to red.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/babb4dbe7c7c482286d990b9fafba9da?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
