{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map colors countries by economic classification, with a hover effect highlighting regions and a color legend displaying category ranges. Built with D3 v5, the example uses d3.geoPath with a natural Earth projection to render the map, while d3.scaleOrdinal and schemeSpectral assign colors to discrete economy values from the world-atlas dataset. Interactive zooming is enabled via a d3.zoom event, and the SVG output includes tooltips showing country names and their economic group. The visualization loads geographic data from TopoJSON and TSV sources.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9d35d0dde3b343f090a61e6709d9d76a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
