{"version":"1.0","type":"rich","title":"Choropleth Map with Interactive Filtering","description":"A choropleth map displays global economic classifications using an orthographic projection that auto-rotates over time. Users can click color legend items to filter countries by economy type, dimming non-matching regions while highlighting selected ones. The visualization uses d3.geoPath for map rendering, d3.zoom for pan and zoom interactions, and d3.forceSimulation-style timers for rotation. Geographic data comes from world-atlas TopoJSON files loaded via topojson.feature, with economy data merged from TSV metadata. Hover tooltips show country names and values through SVG title elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1d611408df224603a9fc42a25eb19a8d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
