{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map colors countries by their economy classification using an ordinal color scale based on `d3.scaleOrdinal` and `d3.schemeSpectral`. The visualization also includes an interactive color legend, built with reusable D3 components, that allows users to filter countries by clicking on a category. Geographic boundaries are rendered as SVG paths using `d3.geoPath` with a natural Earth projection, while the data comes from the World Atlas TopoJSON and TSV datasets. Zooming is enabled through `d3.zoom`, and hovering highlights individual countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a2e656333dba47bf8dc05898c6f89a31?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
